Hum-itate

"Mom, why don't you ever hum-itate?"
"Hum-itate? Um, I'm not sure. What is hum-itate?"
"You know, where you close your eyes, hold your hands like this and say, hmmmmmm."
I look over my shoulder to the backseat and see this:

"You should try it. Sometimes, when you're not looking, I float. But only when you're not looking. Ninjas float all the time when they hum-itate but I'm not a real ninja. (big pause) Yet."
