Knights Must Fall is a 1949 Bugs Bunny cartoon which is a spoof of the 1937 movie Night Must Fall. It was animated in 1948.

In the cartoon, Bugs drops a partially eaten carrot in the backseat of Sir Pantsalot's armor so they commence a joust.

Censorship

The ABC version of this cartoon cuts the part after Bugs hits the Black Knight's head with a hammer after removing the top of the Black Knight's helmet, producing a big lump on the Knight's head.
