Not too bad of a job if you find decent kids. Good way to get some spending money, that's for sure. I just had a fun experience today, wherein I realized what they're really paying me for:

Now for my favorite conversation of the day: (keep in mind that I've prepared food for them a number of times before)

4-year-old girl points, "What's that?"
I reply, "A zit."
"What?"
"A pimple. It's just something that teenagers get."
"Are you a teenager?"
"Yup."
"Does that mean you can cook?"
