Supermarket

A woman goes to the supermarket. She starts walking up and down the aisles. Each aisle she goes to she touches her head, her ears, her breasts, and her crotch. After doing this a number of times a man approaches her and ask if she is having a problem.

She tells him no. He says that he would like to know what she is doing at the beginning of each aisle. She says she is trying to remember her grocery list. He seems puzzled and asks her for an explanation. She goes through the motions saying: "One head of lettuce, 2 ears of corn, 2 breasts of chicken, and food for my pussycat."
