I've mentioned before how answering a question with the words "Your mom" can sometimes get a person in trouble. I don't care. I still say it because it's funny. It's one of those things I'll probably be saying when I'm 80.
That said, I recently had another instance where it could've gotten me into trouble. It didn't, but it could've.
My kids' step-dad: You get all that for the low, low price of twenty-five cents.
Togers: Wait. What only costs twenty-five cents?
Me: Your mom.
I have to say that nothing beats implying that your ex-wife is a cheap whore in front of your children**, your ex-wife and her husband, and getting laughs from everybody.
*This just happens to be the song stuck in my head right now, so it's not meant to be a statement about my ex.
**Not that they'd understand the implication.
