 On a grill, I know. I see grill marks. I say, Daddy's happy. And then, leave me alone. I'm about to have seven hot dogs and feel disgusting. I don't think anybody should look at me. Well, the eye test for hot dogs, when I'm doing chicken, just like the grill, I've got a thermometer that I put in there and make sure it's the correct temperature. You thermometer a hot dog?
