A pun a day keeps your friends away.

Scene: Eight at night. My apartment.

Phone: Ring!

Me: Bonjour!

Farm Boy: I think you mean bonsoir - or wait - bonne nuit!

Me: Actually, I think you say bonne nuit just when you're going to bed - now would be bon soir.

Farm Boy: Great. I just showed how stupid I am.

Me: No, no. You showed your knowledge of the language, just not the idiom.

Farm Boy: Well, now I feel like an idi-ot.

Me: Ha ha ha ha ha!
