I was the R on a kid's football game 2 seasons ago. It was an extravaganza, meaning that this one town had home game after home game - their team in each division. And part of the weekend is to have a BBQ set up, announcing player's names, etc...
These guys were 9 and under. Like basketball, I keep it short, but at the end I did ask if anyone had any questions. One kid put his arm up (good parenting, btw), and asked, "Can I get a hotdog?"
He also happened to be an obvious offensive linesman.
