Passage: His on-air return finally took place at the WWF's Super-Stars & Stripes Forever USA Network special on March 17, 1991, when he came out to shake the hand of The Big Boss Man after an altercation with Mr. Perfect. The following week, at WrestleMania VII, he came to the aid of the Boss Man in his match against Mr. Perfect. Roussimoff finally returned to action on April 26, 1991, in a six-man tag-team matchup when he teamed with the Rockers in a winning effort against Mr. Fuji and the Orient Express at a house show in Belfast, Northern Ireland. On May 10 he participated in a 17-man battle-royal at a house show in Detroit. (won by Kerry Von Erich) Making it his last WWF match. His last major WWF storyline following WrestleMania VII had the major heel managers (Bobby Heenan, Sensational Sherri, Slick, and Mr. Fuji) trying to recruit Roussimoff one-by-one, only to be turned down in various humiliating ways (e.g. Heenan had his hand crushed, Sherri received a spanking, Slick got locked in the trunk of the car he was offering to Roussimoff and Mr. Fuji got a pie in his face). Finally, Jimmy Hart appeared live on WWF Superstars to announce that he had successfully signed Roussimoff to tag-team with Earthquake. However, when asked to confirm this by Gene Okerlund, Roussimoff denied the claims. This led to Earthquake's attacking Roussimoff from behind (injuring his knee). Jimmy Hart would later get revenge for the humiliation by secretly signing Tugboat and forming the Natural Disasters. This led to Roussimoff's final major WWF appearance at SummerSlam '91, where he seconded the Bushwhackers in their match against the Disasters. Roussimoff was on crutches at ringside, and after the Disasters won the match, they set out to attack him, but the Legion of Doom made their way to ringside and got in between them and the Giant, who was preparing to defend himself with one of his crutches. The Disasters left the ringside area as they were outnumbered by the Legion of Doom, the Bushwhackers and Roussimoff, who struck both Earthquake and Typhoon (the former Tugboat) with the crutch as they left. His final WWF appearance came at a house show in Paris, France, on October 9. He was in Davey Boy Smith's corner as the Bulldog faced Earthquake.
