“Did you hear about the English teacher who went to jail? She got a full sentence,” “I wanted to marry my jailed English teacher, but you can’t end a sentence with a proposition” and “Prison may be just one word. But to others, it’s a whole sentence” are similar jokes.

Prison inmates form bonds
unlike any other.
They’ve been known to finish
