Words

Why is it that some words sound so funny? We're having a nice fire in the fireplace, and there are some nice coals, and I was wishing we had some marshmallows. I had gone to the store today, but only to Trader Joe's, and I don't think they have them, even if I'd thought to look. I mentioned this to Mr. Beisbolfan, and he said that if they did have them, they'd probably be made of tofu. I said "tofarshmallows?" For some reason that word struck us as extremely funny. I'm reminded of Dave Barry's example: Newt Gingrich wearing a necktie: not funny. Newt Gingrich wearing a neck weasel: funny.
