The father and son are in the hotel lobby when they spot an elevator.
"What's that Paw?" The boy asked.
"I ain't never seen me nothin' like that in my life" replied the father.
Seconds later an old frail woman walks in the hotel door and hobbles to the elevator. She presses the button with her cain, waits for the doors to open and gets in.
The father and son, still amazed by this contraption, continue to watch.
They hear a ping noise and the doors open again. Out steps a beautiful 20 year old busty blonde.
The father looks at his son and says "Go get your Ma!"
