It's a joke, son

A friend of mine was TA-ing for a professor who apparently had a really bad sense of humor. He was so bad that after telling a story and not getting the response he had expected, he would inevitably say, "It's a joke, son!". That line became an inside joke among his assistants who were having so much fun with it that it sort of spilled and took a life of its own.

So before I crank out the real post I promised you in response to my previous entry I will have to say this much to you: it's a joke, son. :)
