Bill the Duck

A duck walks into a drugstore and says to the pharmacist, "Gimme a chap stick."

The pharmacist asks the duck, "Will that be cash or charge?"

The duck replies, "Just put it on my bill."

The next day, the duck goes back to the drugstore and says to the clerk, "Give me a box of condoms."

The clerk says, "Do you want me to also put them on your bill?"

The duck says, "Hell no, I'm not that kind of duck!"
