New York-based comedian Rodney Dangerfield (1921-2004) often told a self-deprecating joke about going into a bar:
 
“The bartender asked me, ‘What’ll you have?’ I said, ‘Surprise me.’ He showed me a naked picture of my wife.”
 
The joke was part of Dangerfield’s routine by at least the 1980s, and it’s been reprinted in several joke books.
