Because they feel like it, a lot of people eat hamburgers when they're hungry, but I have heard many of those people say they feel like a hamburger and, when I touch their skin, they don't feel even remotely like a hamburger.
I don't want WMC to accuse me of hot-dogging it while he's gone. And, by the way, if I had left the "of" in my cute lil' limerick, it would have ruined the meter.
