Card 28 of 82
A Mysterious Call
A man is lying awake in bed. He makes a phone call, says nothing, and goes to sleep.
Solution: He is in a hotel and cannot sleep because the man in the next room is snoring. He calls the snorer (in this hotel, as in many others, the phone numbers are based on the room number). The snorer wakes up and answers. The first man hangs up without saying anything and goes to sleep before the snorer starts snoring again.
