In the summer of 1991, Skinner debuted in the WWF as an alligator hunter from the Florida Everglades. He was portrayed as a generally nasty individual, always chewing on tobacco and sometimes spitting it on his opponent. He carried an alligator claw to the ring with him, which he would often use as a weapon against his opponents. He competed in the 1991 King of the Ring tournament, defeating Virgil in the first round, but losing to Bret Hart in the second round. While still being billed as undefeated, he challenged Hart for the WWF Intercontinental Championship at This Tuesday in Texas on December 3, 1991, but lost by submission. Skinner competed in the 1992 Royal Rumble, lasting 2:13 before being eliminated by Rick Martel. At WrestleMania VIII, he was defeated in one minute and eleven seconds by Owen Hart.
Skinner competed in the 1993 Royal Rumble, but was eliminated by Mr. Perfect at the 3:05 mark. While in the WWF, Skinner also portrayed Doink the Clown on occasion. At WrestleMania IX, Skinner helped the original Doink defeat Crush by attacking Crush dressed as Doink during the match. Skinner left the WWF in April 1993.
Along with Bobby Eaton, Skinner, as Steve Keirn, wrestled in World Championship Wrestling (WCW) in 1994 in a tag team known as "Bad Attitude". The team made little impact, losing dark matches to Brian and Brad Armstrong at Bash at the Beach 1994 and Fall Brawl 1994. While in WCW, Keirn was also involved in an angle in which masked men attacked Hulk Hogan. Several times in October 1994, Keirn wore a black mask to attack Hogan during and after Hogan's matches.
His last match was on December 10, 2007 at the 15th Anniversary Raw participating in a battle royal where he was eliminated from the match by Sgt. Slaughter.
