The character Dave Chappelle plays in “Home Improvement” is a one-episode character called Dave, which, to be fair, isn’t a surprise in a show that features Tim Allen playing a guy called Tim. Per Vulture, Tim and Dave sat down for an episode of the show-within-show, “Tool Time,” in order to discuss assorted relationship matters with another one-off character, Jim (played by Jim Breuer, because hey, a naming theme is a naming theme).
Chappelle’s few minutes of screen time ended up impressing the higher-ups so much that he — along with Breuer, who was eventually fired and recast — was promptly ushered into a spin-off show called “Buddies,” which was eventually canceled after just five episodes … though a handful of unaired episodes later made their way into the world, as Chappelle’s fame grew.
Fortunately for Chappelle, the belly flop failure of the 1996 sitcom was hardly the end for his showbiz career. As for Breuer, he might have been fired from “Buddies,” but he kept himself busy as a cast member of a little-known revue show called “Saturday Night Live.”
