TNA: Kip James ,Part 4

In a 2001 match on Sunday Night Heat, Sopp was defeated by Chuck Palumbo, who recently left the WCW/ECW Alliance and joined the WWF. After the match, Sopp suggested that they form a tag team. Palumbo agreed and Billy and Chuck quickly rose to the top of the tag team division. They also grew increasingly affectionate toward each other, showing evidence of a (kayfabe) homosexual relationship.

In February 2002, Billy & Chuck defeated Spike Dudley and Tazz to win the Tag Titles for the first time as a team. After winning the titles, Billy & Chuck found a "Personal Stylist" in the ambiguously flamboyant Rico. After defeating The APA, The Dudley Boyz, and The Hardy Boyz in a Four Corners Elimination Match at WrestleMania X8, and Al Snow and Maven at Backlash 2002, Billy & Chuck feuded with Rikishi. At Judgment Day 2002, Rikishi & Rico (Rikishi's Mystery Partner of Mr. McMahon's choosing) defeated Billy & Chuck for the Tag Titles after Rico accidentally hit Chuck with a Roundhouse Kick. Billy & Chuck quickly won the titles back two weeks later on SmackDown with Rico's help. They held the championship for about a month before losing it to the team of Edge and Hulk Hogan.

Later that summer, after Sopp lost a match to Rey Mysterio, Chuck proposed to Sopp asking him to be his "partner for life" and gave him a wedding ring. Sopp agreed, and Billy & Chuck became the most-talked-about duo in the WWE. On the 2002 season premiere of SmackDown!, Billy & Chuck had their wedding ceremony. However, just before they tied the knot, they revealed that entire ordeal was a publicity stunt and disavowed their on-screen homosexuality, admitting that they were just friends. Afterwards, the "preacher" revealed himself to be RAW General Manager Eric Bischoff (who was wearing a skin mask), who then summoned Three Minute Warning to beat up Billy & Chuck. Rico, furious that Billy & Chuck gave up their gimmick, became the manager of Three Minute Warning and defected to RAW. At Unforgiven 2002, Three Minute Warning defeated Billy Gunn & Chuck Palumbo, and due to prematch stipulation, SmackDown! General Manager Stephanie McMahon had to perform H.L.A. (Hot Lesbian Action). Their final match together occurred on SmackDown! in the first round of a tournament for the newly created WWE Tag Team Championship. They lost the match to the team of Ron Simmons and Reverend D-Von. Afterwards, Sopp took a few months off because of a shoulder injury and the team of Billy & Chuck quietly disbanded.

After returning in the summer of 2003, Sopp reprised the "Mr. Ass" gimmick and Torrie Wilson became his new manager. He then started a feud with Jamie Noble which led to an "Indecent Proposal" Match at Vengeance 2003. Noble won the match and due to stipulation, won a night with Torrie. On SmackDown!, it looked as if Torrie was going to have a Ménage à trois with Noble and Nidia until Sopp broke into the hotel room ready to brawl with Noble. When the cameras came back, all four of them were laying in bed after having a foursome. Sopp then started a short lived tag team with Noble before taking time off again because of shoulder injury.

Sopp returned to action at the 2004 Royal Rumble, lasting almost six minutes before being eliminated by Goldberg. Sopp then wrestled mainly on WWE Velocity, before forming a tag team with Hardcore Holly, which quickly rose to the top of Smackdown!'s tag team division. At Judgment Day 2004, they unsuccessfully challenged Charlie Haas and Rico for the WWE Tag Team Championship. Sopp then had a short feud with Kenzo Suzuki before challenging for the WWE United States Championship.

In September 2003, Sopp was reportedly "found passed out" at an airport and WWE sent him to a drug rehabilitation program. On November 1, 2004, Sopp, along with A-Train and Test, were released by the WWE. At the time of his release, he was one of the most tenured wrestlers with the company, behind only The Undertaker and Shawn Michaels. In June 2005, Sopp gave an interview in which he was heavily critical of WWE and the events that led to his release. Many of the negative comments were directed towards Triple H, who Sopp claimed "runs the show up there". Ironically, in January 2007 interview, Sopp broke kayfabe and stated that he left WWE under good terms, and would gladly return if the money was right. Several pro-wrestling websites have reported that Sopp has received much backstage heat in TNA for these comments.
