Dispatching her ten-year-old son to pick up a pizza, my sister handed him money and a two-dollar coupon.
Later he came home with the pizza and the coupon.
When asked to explain, he replied, “Mom, I had enough money. I didn’t need the coupon.”
The duck goes into the drugstore to buy some Chapstick, and the cashier asks how he’s going to pay for it. The duck says, “Put it on my bill.”
