A man wakes up in the middle of the night and wants a snack, so he goes downstairs, gets out a sandwich and a glass of milk from the refrigerator. He eats the sandwich and drinks the milk, then turns out the lights and goes to bed. In the morning, there are dead people on his lawn. Why?
It was never said that he turned on the lights. The man lives in a lighthouse, so when he turned off the light, the people in the boats couldn't see and sailed into a cliff.
