That Comes With A Slightly Heavier Fine

(I’m at a party, mostly attended by parents. It’s late, many guests are drunk, and jokes have become a bit raunchy accordingly.)

Host: “Come on, behave! From now on, whenever someone has a dirty thought, they have to pay one Euro. If they need to voice anything dirty, it’s ten. We’ll be able to build a house with all that money!”

Guest #1: “Define dirty. My views might not be the same as yours.”

Guest #2: “Right! If I think of children playing in mud, does that count as dirty?”

Guest #3: “Hopefully not.”
