What's Your Favorite Food?

This is a fairly simple question that usually gets a fairly simple answer from kids...pizza, ice cream, etc. Well yesterday I was in second grade taking roll. The game was that I sing their names and then they sing back to me their favorite food. So we're going along and it's all the usual favorite food items. Then we get to Joey. I sing "Jo-ey" and he sings "Octopi." WHAT!? That's right he not only likes octopus but he pluraled it and everything. I don't even know how to spell that word (so please no nasty comments about my spelling). Kids are so weird! I LOVE IT!
