Huh?

Joshua came up to me just now, asking me to watch him take his head off. Okaaaay. I watch him try in vain to pull his head off. "Mommy", he says sorrowfully, "it won't come off." It took everything I had to remain somber, trying hard not to laugh at his seriousness. I wonder what made him think that his head would come off, and then I wondered what he would do with it if it could come off. Better leave that one alone. I really don't want to know the answer to that.
