A man coughed violently, and his false
teeth
shot across the room and smashed against the wall. “Oh, dear,” he

said, “whatever shall I do? I can’t afford a new set.”
“Don’t
worry,” said his friend. “I’ll get a pair from my brother
for you.”
The next day the friend came back with the teeth, which
fitted
perfectly.
“This is wonderful,” said the man. “Your brother must be a
very good
dentist.”
“Oh, he’s not a dentist,” replied the friend,
“he’s an
undertaker.”
