Pretty sure he was BORN Jewish.
It is a known fact that in several episodes (can't remember the specific ones) one can see, (in slow motion) that the Roadrunner is also a Jew, since he will briefly and surreptitiously hold up a sign that read, "Kill the Goyim Wherever You Find Him!"
And let's not even talk about Star Trek, which has been used by Jews across the world to transmit secret messages between them and to steal money.
Do you have a link? I can’t find any evidence. Thanks.
