A man walked into a bar and ordered ten pints of Guinness, which he proceeded
 to drink, one after the other, draining each one straight down.  The barman
 said to him, "Steady on. What's happened to you?"  The man replied that he had
 just experienced his first blow job.
 
 Knowing what a momentous occasion that was for a guy, the barman offered to
 buy him another drink to celebrate.
 
 "No, thanks," said the man.  "If those ten don't get rid of the taste, another
 one's not going to help."
