Big Top Bunny is a 1951 Warner Bros. Merrie Melodies theatrical cartoon short directed by Robert McKimson and written by Tedd Pierce.

At Colonel Korny's World Famous Circus, Bruno the "Slobokian Acrobatic Bear" - who, evidenced by his accent, is clearly Russian - is the star of the show.

However, Bugs soon starts getting the better of Bruno, which includes turning the tables on the bear by letting him fall from the trapeze into the band section (twice).

After telling Bruno he's "too clumsy", Bugs starts playing up the idea that he's going solo and will be the star of the show; to prove it, he'll take a 200-foot dive into a tank of water.

A 3-D version of this cartoon was produced in 1972 by General Aniline & Film (GAF) for its View-Master line, spread out over three reels (21 images).
