Guy goes to the doctor, says, "Doc! Doc! You gotta help me! My damn dick turned bright orange!"
The doctors says, "Really? Oh my, I've never heard of that before. Let's take a look."
So the man drops his pants and underwear, and sure enough the doctor sees the brightest, orangest penis he's ever seen.
"Hm," says the doctor, "do you now or have you ever by any chance worked in a dye factory?"
"Nah, never done that for work" the man replies.
"Well," the doctor continues, "do you work with any dangerous chemicals?"
"Nope, sounds too scary, wouldn't do that either" says the man.
Stumped, the doctor then asks, "Ok, do you work with radioactive materials then?"
"No, Doc, you don't get it!" the man retorts, "This can't be work related, gotta be something else! I've been unemployed for months now, all I do is sit around the house eating Cheetos and watching porn!"
