What did you just say?

I was driving to the local park today with my children and we made a pit stop at the gas station for some nutrition. It was doughnuts. My son, Tanner asked me what we were going to get there, when I told him what I wanted, he said "I can't have sugar dad, you know it's bad for my uvula." I must have laughed for like five minutes. He says the funniest things.
