Rabbit Test is a 1978 American comedy film about the world's first pregnant man, directed by Joan Rivers and starring Billy Crystal in his film debut.
Hare-um Scare-um is a 1939 "Merrie Melodies" cartoon directed by Ben Hardaway and Cal Dalton, and first released on August 12, 1939 by Warner Bros. It marks the third appearance of the Bugs Bunny prototype and the first time he, thanks to a redesign by Charlie Thorson, appears as a grey rabbit instead of a white one.
 The title is a homonym with an old nonsense expression ("harum-scarum", meaning reckless or irresponsible) that has nothing to do with rabbits as such.
 Apart from this, the rabbit's voice and laugh were identical to those of Woody Woodpecker in his very first appearance (the Andy Panda cartoon "Knock Knock", released the following year).
 This is also the final cartoon to have a banner on the Warner Bros logo.
