In Adam Sandler's 1998 romantic comedy, The Wedding Singer, an uncredited Jon Lovitz has a brief cameo as a wedding singer, er, that is, not the one of the title. Another one. In his precious few minutes onscreen, he manages to create a character that's sleazy, full-of-himself, arrogant, unpleasant, pathetic AND a bad singer. Bravo, Mr. Lovitz!
