I was watching a Family Guy clip on Youtube and there was a reference by a newscaster to "The Clitoris: Nature's Rubik's Cube".
My 15-year-old overheard this and sasy, "What was that?"
Me: "Nature's Rubik's Cube"
Him: What is?
Me: um, Panda nipples.
Him: Why?
Me: Do you claim to understand them?
Him: No, seriously. Why are they nature's Rubik's Cube?
... So I sigh and play the clip again, and he says,
"What's a clitoris?"
...
