Bumpy Car Ride

There were three guys in a car. One driving, the other in the passenger seat and one resting in the back. The guy in the back became sleepy and fell asleep. A few minutes later, he is startled by a "THUMP THUMP."

"What the hell was that?" he shouted.

The driver says, "It was just a redneck."

"I felt two thumps, though," says the passenger.

"Yeah we had to go through the fence to hit him."
