A man went skydiving for the first time. After listening to the instructor for what seemed like days, he was ready to go. Excited, he jumped out of the airplane. About five seconds later, he pulled the ripcord. Nothing happened. He tried again. Still nothing. He started to panic, but remembered his back-up chute. He pulled that cord. Nothing happened. He frantically began yanking both cords to no avail.
Suddenly he looked down, and he couldn't believe his eyes. Another man was in the air with him, but this guy was going up! Just as the other guy passed by, the skydiver yelled, "Hey, do you know anything about skydiving?"
The other guy yelled back, "No! Do you know anything about gas stoves?"
