Two drunken men knocked on the door of their third friend, who too was drunk.
“You know what!” said one of the two callers. “Yesterday we saw a dead man and thought it might be you!”
“I see,” responded the third friend. “What kind of trousers did he wear?” he asked.
“Gray and with dark checks.”
“Did he wear a blue necktie?” asked the third friend.
“No, a red one.”
“Did he have slippers on his feet?
“No, full shoes.”
“Thank god!” exclaimed the third friend with great relief. “Then that was not my dead body!”
