Unlucky Parachutist
A man is skydiving, enjoying his free-fall, when he realizes that he has reached the altitude where he must open his parachute. So he pulls on the rip cord, but nothing happens.
“No problem,” he says to himself, “I still have my emergency chute.” So he pulls the rip cord on his emergency parachute, and once again, nothing happens.
Now the man begins to panic. “What am I going to do?” he thinks, “I'm a goner!”
Just then he sees a man flying up from the earth toward him. He can't figure out where this man is coming from, or what he's doing, but he thinks to himself, “Maybe he can help me. If he can't, then I'm done for.”
When the man gets close enough to him, the skydiver cups his hands and shouts down, “Hey, do you know anything about parachutes?”
The other man replies, “No! Do you know anything about gas stoves?”
