The Word the Devil Made Up
The old Devil looked around Hell one day and saw that his place was short of help, so he thought he'd run up to Heaven and kidnap some angels to keep things running till he got reinforcements from Miami.
Well, he slipped up behind a great crowd of angels on the outskirts of Heaven and stuffed a couple of thousand in his mouth, a few hundred under each arm, and wrapped his tail around another thousand. And he darted off toward Hell.
When he was flying low over the earth looking for a place to land, a man looked up and saw the Devil and asked him, "Old Devil, I see you have a load of angels. Are you going back for more!"
Devil opened his mouth and told him, "Yeah," and all the little angels flew out of his mouth and went back to Heaven. While he was trying to catch them, he lost all the others. So he had to go back after another load.
He was flying low again and the same man saw him and said, "Old Devil, I see you got another load of angels."
Devil nodded his head and mumbled, "Unh hunh," and that's why we say it that way today.
