“What’s the difference between a large chested lobster and a dirty bus stop?” (joke)

A popular joke—so bad it’s been called a “dad joke”—is:
 
Q: What’s the difference between a dirty bus stop and a lobster with breast implants?”
A: One’s a crusty bus station, and the other’s a busty crustacean.
 
“What’s the difference between a lobster w/ a boob job and a greyhound bus stop? 1’s a crusty bus station, 1’s a busty crustacean” was posted on Twitter on August 11, 2009. “Crab” is sometimes used instead of “lobster.” “Whats the difference bewteen a crab with big tits and a Greyhound Bus terminal? Ones a busty crustation, and the others a crusty bus station” was posted on Twitter on March 5, 2010.
 
The joke has been printed on many images.
