A hired gun gets on a private plane to his next contract. Halfway through the trip, he notices the plane rapidly losing altitude. So he opens that back of the plane and starts tossing out everything he doesn't need. Grenades, guns, ammo unless it was bolted down it went out. He stopped throwing things out when the plane started to regain altitude. When the plane lands, he sees some kids giggling on the side of the road. "What's so funny?", he asks. "Daddy farted and the house blew up," said a singed little boy.
What is Stephen Hawking' favourite song
Head shoulders screws and bolts
What does a robot do at the end of a one night stand? -- He nuts and bolts.
