Burgers are cows? No, Thank you!

We watched, Cloudy with a Chance of Meatballs, the other day. Rowen wanted the burgers like the ones that rain in the movie. So we had burgers for dinner tonight. We don't eat meat very often so I figured it would be a nice treat, if you will. After Rowen had eaten half a burger and was eating another 1/4 of one, Brandon told him it was a cow (it was Bison but he knows more what a cow is). Well, he no longer wanted to eat. He was ready to take a bite and then dropped it on to his plate after Brandon told him what it was. He said "I don't like cow". Hahaha...his face was priceless. It was just full of disgust.
