My kids are pretty strange too. Here's an exchange my daughter told me about from her college Spanish class (you have to imagine all of this transpiring in fluent Spanish - it's a 400 level conversational class for the kids going to study abroad):
They were discussing a short story about shrunken heads.
Boy in class: "How do you shrink a head, anyway?"
Daughter (raising hand): "I know! I know!" Whereupon she explains the process.
Professor: "Where on earth did you learn THAT?"
Daughter: "My mama told me."
Professor: "How does your MAMA know that?"
Daughter: "Uh . . . she's travelled a lot. . . "
The whole class was roaring. The Spanish prof wants to meet me - can't imagine why.
