Bugs Bunny's Birthday

Well, sort of.

April 30, 1938:

The animated cartoon short Porky's Hare Hunt debuts in movie theaters, introducing Happy Rabbit (a prototype of Bugs Bunny).
Bugs' Bunny was an unnamed rabbit before he was evolved into Bugs Bunny. It was also named Happy Rabbit.
The rabbit's first appearance was essentially the same as the early Daffy Duck. He appeared in four cartoons before finally becoming the well-known character of Bugs Bunny in Tex Avery's A Wild Hare.
Several published first person accounts, encyclopedic references, and Warner Bros.' own published material describe the inception of the name and of the character. A model sheet by Ben Hardaway describes this prototype character as "Bugs' Bunny" (note the apostrophe) but in most of the cartoons the character is unnamed.

Looney Tunes were always my favorites growing up.
