A Northern couple was visiting the deep south had stopped along a dark back road for a rest.

All at once there was a tapping on the window. The women screamed "I think there is a ghost tapping on the window!" Sure enough a wizened face with long flowing white hair was there just out side the window.
The husband stared the car and shoved his foot down on the gas and immediately was doing 60 miles and hour.
"Step on it!" shrieked the wife, "He's still out there!" And sure enough, there was another tapping at the window.
The husband shoved his foot to the floor again! This time he was doing ninety (90) miles an hour.
Still the ghostly figure tapped on the window.
"You better giver 'er some more gas!" "He's still out there."
"I can't go any faster, I've got her up to 120 miles an hour.
About that time the redneck motioned for the passenger to roll the window down, which he did.
"Say!" "I was wanting to know, do you need a shove to get out of this mud hole?"
