Elevator
A country bumpkin family from Alabama decides to go to the Big Apple for the first Time in their lives; Maw, Paw and their son. They go into the Empire State Building. As they're walking around they notice the elevator. Never seeing one before they stand in front of it bewildered.
While staring at it, an old lady in a wheelchair rolls up to it, pushes the button, the door opens, she rolls herself inside and the door closes.
The Alabama hick family watches as the lights for each floor light as it goes up. They continue to watch as the numbers go down again.
The door opens and out walks this tall gorgeous blonde. Legs to her neck. Great figure. Beautiful!
Paw looks at his son and says, "Quick boy, shove yer Maw in there!!"
