An idiot was taking sky-diving...

An idiot was taking sky-diving lessons. The instructor explained that it was time for his first jump, and all he had to do was jump from the plane, count to six, and pull the rip cord. A truck would be waiting for him in the field where he would land.
The man jumped from the plane when he was told to, and counted to six. When he pulled the rip cord, the parachute wouldn't open. He tried the reserve chute and that didn't open.
Frustrated, he muttered to himself as he fell, "I'll bet the damn truck won't be waiting for me either."
