Ehhhh... What's up, docs? Looks like there is some stuff out there about Bugs Bunny possibly being Jewish. Let's see if we can figure this one out.

Rabbits are not kosher
Bugs passes our Berenstein Bears Law, so it's possible that he could be Jewish.

Bugs speaks with a New York accent
Not all New Yorkers are Jews. Sorry, rest of the country.

Bugs was partly based on Groucho Marx, Jew
A point for the Jew camp.

Bugs was voiced by Mel Blanc, Jew
Normally, that will give the Jew theory more traction, but Blanc voiced pretty much every Looney Tunes character... including Porky Pig. And we're not having Porky Pig, thank you very much.

Bugs' original name was Happy Rabbit
Let's face it, the odds for a Jew to be (named) Happy are quite low.

Bugs' two main enemies, Elmer Fudd and Yosemite Sam, are obvious goyim
Can't argue there, but why would that make Bugs Jewish?

So, as you see, there's just not enough evidence to proclaim him a Jew. Of course, that hasn't stopped us before. Except for one very important thing:

We proclaimed Daffy Duck as Jewish
And having both Daffy and Bugs as Jews just seems prepothterous... Sorry, docs.
