This Catholic nun gets it

[Minimalist]

A priest is doing some community work downtown

...when he is propositioned by a hooker.
"Hey Father, I'll give the best blow job of your life for $10."
Confused, the priest replies "No thank you, my dear."
Later, back at the church, he approaches one of the nuns.
"Sister, this is kind of embarrassing, but what's a blow job?"
"Oh, you know," says the nun, "$10, same as downtown."
