Three guys are in a Cessna.
The first drops a penny out the window.
The second drops a pencil and the third a bomb.
When the plane lands, the first guy goes to see where the penny landed.
He sees a guy swearing and trying to get a penny out of his forehead.
The second sees a girl holding her dog who has a pencil through his head.
The third guy sees a guy laughing his head off.
He asks, “Why are you laughing?”
The guy says, “I was cooking on my BBQ when I farted…”
“What’s so funny about that?”
“It blew my neighbor’s house apart!”
