Bank and Zoo

　　　　When I was waiting in line at the bank, I noticed a woman holding a small child at one of the windows. The boy was eating a roll, which he thrust at the teller. The teller smiled and shook his head.

　　　　"No, no, dear," said the boy's mother, and then, turning to the teller, "I beg your pardon, young man. Please forgive my son. He's just been to the zoo."
