Leaving my mind on idle, unsupervised......

Scenario: Tom Sawyer and his friends, in their later years, go to visit a radio studio. They look around at all that is new and different since the pre-Civil War days of their childhood.

Finn is particularly fascinated with the table of various gadgets, boxes and machines used to make live sound effects. He turns to his friend, who has spent far more years in the big city than he.

"Tom, what do they call that?"
"Foley, Huck!"
