Sexy and I know it...

William: "Mommy, I've made up a new song. Wanna hear it?"
Me: "Sure!"
William: (to the tune of  'if you're happy and you know it...') "If you're sexy and you know it clap your hands, if you're sexy and you know it clap your hands...'
Me: "Um. What does sexy mean?"
William: "You don't know what it means?"
Me: "I think I know what it means but I want to hear what you think it means."
William: "It means wealthy. It means you are VERY wealthy."

Well ok then. We might just
go with that for now. And I'll add it to the growing list of things I
probably should have explained
right away but decided not to because his interpretations were
just so stinking cute.
