The Bugs Bunny Mystery Special is an animated television special that was broadcast on CBS October 26, 1980. Presented as an Alfred Hitchcockstyle whodunit, the plot is modeled after those of North by Northwest and The Fugitive. Like most Looney Tunes specials of the time, this program consists of clips from classic cartoons with some new original animation holding them together.

Porky concludes the special from inside his jail cell.
