Riddle: One day a man just came home in the morning from the bar last night and he turns on all the lights in his house and reads the newspaper. The newspaper rads; "Last night a boat has crashed and killed hundreds of people." This shocked the man and he pulls out a gun and shoots himself.
Why does the man shoot himself?
Answer: Because he lives in a lighthouse and he just now turns on all the lights which means he didn't have them on last night at the bar.
