A Cock-work Orange
Dan wakes up on Monday morning, staggers into the bathroom and turns on the shower. He begins to lather up and notices that his dick is bright orange. He is really concerned, but it doesn't hurt and he feels normal.
He finishes his shower, gets dressed and goes to work. During his mid-morning break, he goes into the men's room to take a leak. While standing in front of the urinal, a co-worker comes in, sees his dick, and exclaims, "Holy Shit! Your dick is bright orange!"
Dan tells his co-worker that he feels just fine and his dick doesn't hurt. His co-worker advises him to go to the company doctor as soon as possible, since it looks like it could be serious.
Dan goes to the company doctor and, after a thorough examination, the doctor says, "You seem to be fine and all of the tests are normal. Did you do anything out of the ordinary over the weekend?"
Dan scratches his head and says, "No. Not that I can think of. All I did was stay home, watch porno movies and eat Cheetos."
