My wife's kid brother who is no longer anywhere near a kid, had a terrible heartburn problem, and coughed up some blood one day recently so he went to the doctor to get checked out. The doctor told him he was going to have to put an instrument/camera down his throat to take a look down inside just like a colonoscopy. The first thing my brother in law asked him was; Did you at least wash that thing? This was just related to us this morning by a call from my wife's older brother. We are hopeful that he's okay, but his sense of humor still seems to be in good shape.
