Yep. a wacky one. A man was found dead next to a 13 story building. The police say it was a suicide and that he jumped from one of the 13 floors. But you say it was a homicide (someone killed him). To prove this, you go to each floor of the building, open the window, and drop a penny. You do this to each floor until you reach the 13th floor, open the window and drop a penny. How does this prove it wasn't a suicide?
The window would have been left open if he jumped from it. Therefore someone pushed him from the window, then closed it.
He was such a pessimist that his friends considered him a ion tall 3 words This one is so easy that I mixed the words together.
