This is a great movie, even though it's clips from WB cartoons mived with new animation by Friz Freleng. It begins with a showing of Freleng's 1958 award winner "Knighty Knight Bugs", and then shows the following acts:
"Satan's Waitin'": Yosemite Sam lands in Hell after Bugs foils his attempt to court widow Emma. The devil gives Sam three chances to capture Bugs as a replacement.
"The Unmentionables": Bugs parodies FBI agent Elliot Ness, but trouble (and looniness) insures when he tangles with Rocky's gang of thugs.
"The Oswald Awards": Bugs hosts an awards night parody, nominating the Big Bad Wolf of "Three Little Bops" (1957), Sylvester and Tweety, and (!) himself. He wins, much to Daffy Duck's anger.
