Stage Door Cartoon (1944)

Continuity mistake: When the curtain raises before Bugs Bunny does his tap dancing act, you can see the background behind him only has a columned building but in the next shot a mansion suddenly appears.

Elmer Fudd: Which way did he go? Which way did he go?

Trivia: When we see Elmer pointing his gun at Bugs in order to make him do his second curtain scene, you can see behind Bugs a crate saying "5 Clampett Trained Seals" - a reference to the Warner Brothers director, Robert Clampett.
