A man is found dead at the end of an alley. A detective who enters the scene sees the letter X and immediately knows who killed the man and why. What did the detective conclude?
The alley is a bowling alley. The man who was killed was a pin spotter (an old profession where they would reset the pins by hand). The X was the marking on the score sheet for a strike. The detective saw the letter X and knew that the person bowled last, got a strike, and was due to bowl again. But they bowled before the pin spotter could get out of the way.
A man wants to get into a night club where the bouncers test each person before they can enter. The man waits and watches. A woman walks up to the bouncers and the bouncers say 6. The woman replies with 3 and goes in. A small man walks up and they say 12. The man replies 6 and is admitted. The first guy thinks he’s figured it out and walks up. They say 4 and the man replies with 2, but they don’t let him in.
