A fella in his hospital bed keeps ringing for the nurse because he
 has to take a dump really bad.
 
 He can't hold it any more and finally messes in his bed. Desperate
 to  clean it up and avoid embarrasment, he pulls the sheet off the
 bed, wads it up, and tosses it out the window.
 
 Joe, the local inebriate, is on his way to his favorite haunt when
 this sheet happens to land square on his head. He staggers into
 the bar, and the bartender, taking one look and a getting a whiff
 of the brown stuff, sez, "Joe, you smell AWFUL."
 
 Joe sez, "You would too, if you just beat the shit out of a
 ghost."
