Big House Bunny (22 Apr 1950)

Bugs hops in a rabbit hole and comes up in Sing Song Prison. Mistaken for a convict by the prison guard (Yosemite) Sam Shultz, he spends the rest of the film trying to get out of the pen. The scene with the hangman's noose is sometimes edited from television showings.
