This guy walks into his doctor's office complaining of a sharp pain on his forehead. The doctor runs some tests and tells the guy "I've found your problem but you're not going to like the cure - I have to castrate you.". The guy says hell no and leaves. He goes back in several times over the next week or two hoping for a different answer but keeps getting the same one. Finally the pain gets to be too much for him and he goes in and tells the doctor "I can't take this any more - go ahead and take'em doc.". So the doctor does his thing and the guy leaves he office pain-free.
On his way home he walks into a men's store and tells the clerk "I need some new underwear.". The clerk asks what size he wears and the guy responds "32", to which the clerk says "oh no sir - you look more like a 36 or 38. You know, if you wear those things too tight you'll get this pain on your forehead..."
