Lane first appeared in World Championship Wrestling (WCW) as Lane Carlson, a jobber. He made his WCW debut on the April 14, 1997 episode of Monday Nitro by losing to the World Television Champion Ultimo Dragon. He later changed his ring name to Lenny Lane on the May 24 episode of Saturday Night during a match against Buff Bagwell, which Lane lost. He made his pay-per-view debut at the 1998 Slamboree event as a participant in a battle royal to determine the number one contender for the Cruiserweight Championship; he was eliminated by Juventud Guerrera. His first storyline saw him as Chris Jericho's lackey. He later began advertising a product known as "Ab Solution Plus." Lane picked up his first victory in WCW on the October 3 episode of Saturday Night against Lash LeRoux. He appeared in the World War 3 battle royal at the eponymous pay-per-view on November 22 for a future shot at the World Heavyweight Championship, but Kevin Nash won the match.
In June 1999, he approached Lodi and proposed forming a tag team. Lane and Lodi were renamed The West Hollywood Blondes. The Blondes were an effective villainous tag team, though they rarely won matches.
In an upset victory, Lane defeated Rey Mysterio, Jr. on the August 19 episode of WCW Thunder in Lubbock, Texas to win the Cruiserweight Championship. With the assistance of Lodi, he defended the title successfully, including notably against Shaggy 2 Dope of the Insane Clown Posse over the next six weeks. On the October 3 episode of WCW Monday Nitro, Psychosis was announced as having defeated Lane for the Cruiserweight Championship at an unspecified live event.
Lane and Lodi returned as "Standards and Practices", a censorious duo who opposed the "adult themes" present in WCW. In a drastic departure from their previous appearance, they wore designer suits, carried briefcases and were accompanied by a secretary, Miss Hancock. Miss Hancock eventually abandoned the team. Soon the gimmick of Standards and Practices were dropped on an edition of WCW Nitro when both Lane and Lodi stripped off their suit and tie. In the following weeks, they competed under the tag team name 2XS, a gimmick more resembling two hard rock party-goers who wore just jeans to the ring. This gimmick too was short lived as they failed to get over, even in a WCW Tag Team Championship match and were soon pulled off television a few weeks later. Both Lane and Lodi were released from WCW in August 2000. Lane briefly reappeared for a short feud with The Wall in 2001, but was released once more.
Lane appeared on the October 31, 2004 edition of WWE Heat, teaming with Ken Anderson against Rob Conway and Sylvain Grenier, and on the September 30, 2008 edition of WWE's ECW on Sci Fi, losing a squash match to Jack Swagger.
