Desperate Housewives: School Scene

Casting sides hint that Mrs. Henderson's work groups at school causes confusion among parents. It all started with Valerie - a parent who also happens to be an art teacher. Valerie visits Mrs. Henderson's class and asks why her kid's in the giraffe work group. Some of the parents thought that the work groups are based on their kids' intelligence and some thought that the leopard group is the smartest.

This sounds like a total school disaster!
