"I would give the teller a ten and watch them try to make change, lol."

Someone taught with Common Core methods would probably add twelve plus ten and give you $22 change.

That makes me think of the scene from "Paper Moon" where Ryan O'Neal is doing the con job on the cashier.

Practicing the art of distraction. From the 1973 movie "Paper Moon" starring Ryan and Tatum O'Neal.
