So a guy goes to the doctor. The doctor asks, “What seems to be the problem?” The guy, obviously somewhat embarassed says, “Well, it's the strangest thing, but my, um, private parts seem to have turned bright orange.”
The doctor is taken aback - he's never heard of anything like this before. He examines the man, and sure enough, the situation is exactly as the man describes it: as orange as a traffic cone.
“Have there been any significant changes in your life that might explain this?” the doctor asks.
“I don't think so. I mean, my wife left me last week, but nothing medical, if that's what you're asking.”
“Sometimes big changes like that can cause stress, and stress can have odd effects. Have you been feeling depressed, losing sleep, anything like that?”
“Not really - I've been taking it pretty easy. Mostly I just sit on the couch, eat cheese doodles, and watch porn.”
Tim Ewald told me this one when I mentioned that my wife was away at Wharton this week starting her Executive MBA. Being a smartass, he also asked me if my keyboard was orange. :)
