The noder who originally explained this has pulled an asamoth. I am merely recreating his node from memory, (and adding a little from a google search).

Wow! I can't believe I have the honor of recreating this node! MR. T ATE MY BALLS was the meme to end all memes. It inspired many copycat memes such as CHEWBACCA ATE MY BALLS, NATALIE PORTMAN ATE MY BALLS, and even such E2 specific things as EDB ATE MY BALLS. But MR. T ATE MY BALLS was the original.

From the MR. T ATE MY BALLS HOMEPAGE

Mr. T stands there looking thoughtful: "I sure could go for some BALLS right now."

Mr. T is about to punch some poor fool in the face: "GIMME YOUR BALLS FOOL!"

Mr. T with an mmmm good look on his face: "DAMN. Them balls is GOOD!"

Mr. T stands there with his hands on his hips: "I pity the Fool who don't like BALLS!"

Mr. T Ate My Balls actually made an apparence in the print media in Dave Barry's book Dave Barry in Cyberspace. The book actually made fun of the whole emergence and geekiness of the internet (although it was clear that Dave more or less knew his way around).

One of the sections of the book was entitled Selected Web Sites - At last: proof that civilization is doomed. Right there, on page 155, after Guide to Crackers is:

HUMAN TESTICLE CONSUMPTION
Mr. T Ate My Balls
(snip)
There are some things in life that it is better
to just not even think about, and one of those 
things is the question of what, exactly, led to
the creation of these pages.

I'm sure Dave would have a field day with E2.
