Not sure I'd call this false as I distinctly remember it happening, but one of those wrestling specials on Combs FF...it had to be one of the WWF vs. WBF (remember THAT?) episodes. The question was, "Name a kind of wrestling." In revealing the rest of the answers at the end of the round, Ray wonders out loud if "fake wrestling" is one of the answers.
(Perhaps this fits more with "lost" GS moments, as I have yet to see it again online. The 1994-95 episode where Richard reads a letter saying they don't like him nor the "other guy" is like this too)
