New York-based comedian Rodney Dangerfield (1921-2004) wrote in “My Favorite Jokes” for Parade magazine in November 1978:
 
“I saw a sign outside a bar that said ‘Topless! Bottomless!’ I went inside—there was no one there.”
 
The “topless and bottomless” bar joke is still relatively popular, even though such bars have decreased in number.
