Me: I can't believe you spent your day off raking leaves. Leaves suck.

Mom: I told you not to say that. I don't like that expression.

Me: [takes a moment to calculate whether she'll be offended...] You suck.

Dad: Jay! That was very rude. Go and apologize.

Me: I was kidding.

Dad: I know you were kidding. But Mom said she didn't like that expression.

Me: I know. That's the joke.

Dad: I understand that, but still, go apologize to Mom.

Me: [walks over to Mom in the kitchen] I'm sorry, Mom, that you have no sense of humor.
