Now to Mick Foley's appearance on the show, first let's outline how he fits into the show with a quick summary of the episode. "Both couples Cory-Topanga and Angela-Shawn split up Topanga and Angela Move in with Rachael without telling Eric and Jack. So the boys go against the girls to see who gets the apartment and the girls win, and Eric vows to seek revenge on Topanga for beating him up so easily." When the girls go against the boys who appears in the door to be the ref in the match but Mick Foley and he proceeds to beat a little on Eric before the fight starts to show the rules. Most people may not remember it, but this appearance can be seen on the October 1 1999 episode of Boy Meets World and it was also very good because Mick at this point was one of the most popular wrestlers on the roster.
