Before they formed a partnership, John Morrison and The Miz were opponents in WWE, competing for the ECW Championship in October 2007. On the November 16, 2007, episode of SmackDown!, then-rivals Morrison and The Miz were paired together to face Matt Hardy and MVP in a match for the WWE Tag Team Championship, which they subsequently won after MVP turned on Hardy. After winning the title, Morrison and The Miz brought the title to the ECW brand. Soon after winning the WWE Tag Team Championship, the two were no longer portrayed as enemies, but rather as trusting friends. They would defend the title on numerous occasions on both ECW and SmackDown as well as multiple pay-per-views against opponents like Shannon Moore and Jimmy Wang Yang, Jesse and Festus, and Tommy Dreamer and Colin Delaney. The team's gimmick was further expanded upon when they were given a show on WWE.com called The Dirt Sheet. During the sixth annual WWE Draft on June 23, 2008, on Raw, the duo defeated the Hardys (Matt and Jeff) which earned ECW its only draft pick, which turned out to be Matt Hardy. At The Great American Bash in July, Morrison and The Miz lost the titles in a four team tag match to Curt Hawkins and Zack Ryder, ending their reign at 250 days; however, neither The Miz nor Morrison were pinned during the match.
After losing the WWE Tag Team Titles, Morrison and The Miz entered a feud with ECW newcomers Evan Bourne and Ricky Ortiz, who they had previously mocked (and continued to do so) on the Dirt Sheet. They also had an internet-centered feud with Raw's Cryme Tyme (Shad Gaspard and JTG) based on which WWE.com online show was better: the Dirt Sheet or Cryme Tyme's Word Up. Morrison and The Miz won a match between the two teams at Cyber Sunday, which was voted for by fans over a World Tag Team Championship match.
Throughout October, the team mocked D-Generation X (DX) (Triple H and Shawn Michaels), using phrases such as "Are you 50?" instead of DX's usual catchphrase "Are you Ready?" to mock their ages. On the October 28 episode of ECW, their feud with DX continued as they mocked them after a live Dirt Sheet and then proceeded to attack two impostors playing Michaels and Triple H. On the 800th episode celebration of Raw, Morrison and The Miz competed in a match against DX, and were defeated. During the match, they mocked DX's signature moves, with Morrison successfully performing a superkick (mocking Michaels' Sweet Chin Music) on Triple H as well as The Miz attempting a Pedigree on Triple H. Following their feud with DX, they continued to feud with Cryme Tyme. Morrison and The Miz were part of John "Bradshaw" Layfield's team at the annual Survivor Series, but they lost to the team of Shawn Michaels.
On the December 8 episode of Raw, Morrison and The Miz won the 2008 Slammy Award for Tag Team of the Year and also for the Best WWE.com exclusive, for their show, The Dirt Sheet. On December 13, at a house show in Hamilton, Ontario, Morrison and The Miz won the World Tag Team Championship for the first time, defeating Kofi Kingston and CM Punk. The duo then engaged themselves in a feud with The Colóns (Carlito and Primo). They later defended their titles against the Colóns but lost in a match for The Colón's WWE Tag Team Championships. On the pre-show of WrestleMania XXV, Morrison and the Miz lost the World Tag Team Titles to The Colóns (Carlito and Primo) in a Lumberjack match to unify the World Tag Team and the WWE Tag Team Championships.
On the April 13 episode of Raw, The Miz lost a match to Kofi Kingston after Morrison accidentally got Miz disqualified, which gave Raw a draft pick in the 2009 WWE draft. The pick was then revealed to be The Miz, and he subsequently attacked Morrison, ending their partnership. Two days later on April 15, Morrison was drafted to the SmackDown brand as part of the 2009 Supplemental Draft.
In October 2009, WWE premiered a new pay-per-view event based around inter-brand matches. At the time, The Miz was the second-tier champion on Raw after winning the United States Champion and was subsequently booked against SmackDown's Intercontinental Champion, John Morrison. In the build up to their first match since splitting, the two hosted a one-off edition of The Dirt Sheet on the October 16 episode of SmackDown, where the two compared themselves to The Rockers, debating over which is more comparable to the successful Shawn Michaels and which was the less successful Marty Jannetty. At Bragging Rights, Miz pinned Morrison to become the only member of the Raw roster to win an interpromotional match. The following month at Survivor Series, Miz captained a team of five wrestlers against Team Morrison in a five-on-five Survivor Series elimination match and once again bested his former partner. At the Tribute to the Troops in December, Miz rolled up Morrison for the win in a singles match. The two had another match the following March, when John Morrison and his new partner R-Truth challenged for the Unified Tag Team Championships held by The Miz and Big Show. Morrison was finally able to defeat The Miz in a singles match, however Morrison could not pick up the victory for the titles at WrestleMania XXVI.
In 2011, after The Miz won the WWE Championship, he retained the title against Morrison in a Falls Count Anywhere match on the January 3, 2011 episode of Raw. At May's Extreme Rules, John Cena won the title in a triple threat steel cage match against The Miz and Morrison. Later that year in November, The Miz and Morrison had another Falls Count Anywhere match, in which The Miz caused Morrison a scripted injury; this was used to write Morrison off WWE television as he would leave the WWE soon thereafter.
Morrison made his return on the January 3, 2020 episode of SmackDown and was paired with The Miz. On the January 31 episode of SmackDown, the duo teamed together for the first time in nearly eleven years, defeating Heavy Machinery (Otis and Tucker), Lucha House Party (Gran Metalik and Lince Dorado), and The Revival (Dash Wilder and Scott Dawson) in a fatal four-way tag team match, thus earning an opportunity to face The New Day (Big E and Kofi Kingston) for the SmackDown Tag Team Championship at Super ShowDown, winning the titles on February 27.
On March 8, the duo had their first title defense against five other teams in the second-ever tag team Elimination Chamber match at the Elimination Chamber event, eliminating The New Day and The Usos themselves at the end of the match to retain the title. At WrestleMania 36, after the Miz's absence, Morrison defended the SmackDown Tag Team Championships by himself in a ladder match against Kofi Kingston and Jimmy Uso, in which he was successful. On the April 17 episode of SmackDown, the duo lost the titles back to The New Day after Miz unsuccessfully defended the titles by himself in a triple threat match against Big E and Jey Uso, ending their reign at 50 days. At Money in the Bank the following month, Morrison and Miz unsuccessfully attempted to regain the championship in a fatal four-way tag team match also involving Lucha House Party (Gran Metalik and Lince Dorado) and The Forgotten Sons (Steve Cutler and Wesley Blake). Next, Morrison and Miz started a rivalry with Universal Champion Braun Strowman. At Backlash, the duo competed for Strowman's title in a two-on-one handicap match, but lost.
They then began their feud with Otis and Tucker of Heavy Machinery in pursuit of Otis' Money in the Bank contract. The Miz then convinced management to trade Otis' girlfriend Mandy Rose to Raw as a way to "help Otis" so he could focus on cashing in the contract, but after insults, Otis attacked Miz and Morrison. The Miz then threatened to file a lawsuit against Otis if he did not forfeit the Money in the Bank contract. Otis, backed up by Tucker, said he would not forfeit the contract. During the 2020 WWE Draft, Otis remained on SmackDown while Tucker, Miz, and Morrison were all drafted to Raw. Despite being drafted to separate brands, the trial over the Money in the Bank contract commenced on the October 23 episode of SmackDown with WWE legend John "Bradshaw" Layfield (JBL) serving as judge. After the hearing, JBL initially ruled in favor of Otis, but after Miz bribed JBL with a large sum of money, JBL changed his ruling in favor of Miz and ordered that Otis would defend his Money in the Bank contract against Miz at Hell in a Cell. At the pay-per-view, Tucker betrayed Otis by hitting him with the briefcase, allowing Miz to pin Otis and claim the briefcase for himself, thus making Miz the third wrestler to win the briefcase twice, and the second not to do so in the ladder match.
Morrison and Miz then began a feud with WWE Champion Drew McIntyre. Miz cashed in his Money in the Bank contract at the TLC: Tables, Ladders & Chairs event during a TLC match match between McIntyre and AJ Styles, making the match a triple threat in the process, but was unsuccessful as McIntyre retained his title. However, on the December 28 episode of Raw, Miz had the contract returned to him as the cash-in at TLC was ruled invalid due to Morrison cashing in the contract on his behalf (as only the contract holder himself can cash it in). At Elimination Chamber, Miz would successfully cash in on McIntyre and win the WWE Championship for the second time in his career. However, Miz would lose the championship to Bobby Lashley on the March 1 episode of Raw, ending his reign at only eight days. Miz and Morrison started a feud against Bad Bunny and Damian Priest at the end of January, which led them to a match at WrestleMania 37, in which they lost.
On the August 23, 2021 episode of Raw, the Miz was defeated by Xavier Woods by a distraction from Morrison, After the match, the Miz attacked John Morrison, disbanding the team.
