Quantum Leap1989

[Stacker tells the boys how Al came to his nickname "Bingo"]

Stacker:
...He lands wheels-up in this pasture, right? Bangs his head on the gunsight. When he comes to, he looks up and he sees three sets of casabas hangin' over him. He thinks, "Oh, man, it's a concussion."

Plumber:
I wouldn't mind that concussion!

Stacker:
But it's not. It's triplets. We find him the next morning asleep under the wing. I say, "How'd you spend the night?" He says, "Bingo, bango, bongo!"
