Larry Bird

One time in an elevator, this kid hit the wrong button so they had to stop at an extra floor on the way up.

Larry Bird was about two seconds away from uppercutting the kid, so when the kid asked for an autograph, Larry said okay and wrote "your life" in cursive on an old receipt.

Just when the kid had read it, Larry grabbed the receipt back, crouched to the floor and leapt straight up, smashing his head through the ceiling of the elevator.

The kid took off in tears and Larry just sat there moaning.
