Hummm

Three men were flying in a plane, when they decided to drop stuff on the town they were flying over. One dropped a book, one dropped a brick, and one dropped a bomb, just for fun.

They then landed, to survey the damage they caused. The first thing they saw was a small child, crying and holding a book. Then they saw another small child, crying and holding a brick. Then they saw a small child laughing his head off. "What's so funny?" they asked him.

"It was great," he said. "I farted and my neighbor's house blew up."
