A man jumps from an airplane and when he pulls his parachute cord, it breaks.
As he's plunging to his death, he sees a man rising rapidly into the air. As
they cross paths, one falling towards the earth and the other rising away from
it, the skydiver yells, "Excuse me! You wouldn't happen to know anything about
parachutes, would you?"

"Sorry, I don't," the man yells back. "Would you know anything about lighting
gas stoves?"
