a joke I made up today

A woman goes grocery shopping in California. At the store, she's surprised to find a buffalo behind the deli counter, serving customers, but no one else seems to mind so she takes a number and waits for her turn. The whole time, the buffalo chatters constantly about cheese, how wonderful it is, how much he likes it, what kinds he recommends for different orders, no matter whether the customer wants any or not. Finally the woman can't take it anymore and goes to complain to the store manager. She says to the manager, "I can't believe you're letting that buffalo work in the deli!" The manager says, "Lady, that's not a buffalo, that's a Monterey Yak!"
