On Jan. 18, 2007, the final question on the game show Jeopardy was...
A: The middle initial E. of this character introduced in 1949 stands for Ethelbert.
Q: Who is Wile E. Coyote?
Ever wonder where the heck this "fact" came from? It wasn't from a cartoon or anything revealed by Chuck Jones later in life. No, it came from a single 1973 Looney Tunes comic book story. Below you can see the infamous artwork for yourself.
I really doubt this was ever intended to be the character's "official" middle name but thanks to Jeopardy, I am sure this "fact" will be popping up for years to come.
UPDATE: Mark Evanier, author of the "Ethelbert" story, has written more about the subject on his blog.
