on one of the first episodes they play "girls aint nothin but trouble" when carlton and Will are both after the same girl to take to a halloween party. Its also the rare version with different lyrics to the album version.
And lets not forget the credits were Will is rapping, thats every show with Will rapping lol. there are a couple of other times were Will raps or beatboxes, i think they probably showed more of Wills skills than the rest of the casts.
lol i remmember that one were Will and carlton were singing to ashley , Will had that dog puppet lol, that was great. haha and carlton kept talking to his cat puppet, sorry had a bit of a flashback to it, made me laugh.
