Dave Letterman's Tom Hanks Button, REVEALED (VIDEO)
An unannounced Tom Hanks came running onto David Letterman's stage Tuesday night at the touch of a button, leaping over the back of and into the guest chair
After his monologue, Letterman pointed out a small red button on his desk and started flicking it. Seconds later, Hanks sprinted on the stage.
The red switch is a "Tom button."
"I heard the signal, I came a-running," Hanks told Letterman. "I was at a really important fund raiser in Cleveland, please don't press it again unless it's a real emergency."
He left the stage to applause, Dave pushed the button again, and the Hanks sprint, chair leap and confusion happened all over again.
