George Cooper Sr.: Well, I got to warn you, learning to throw isn't something you get right on the first try. It... it takes practice.
Sheldon Cooper: And does this practice involve setbacks and frustration?
George Cooper Sr.: Yeah.
Sheldon Cooper: Perfect.
George Cooper Sr.: Now, you'll notice that the shape of this thing is more like a missile, right, than it is your typical bouncy ball.
Sheldon Cooper: The term you're looking for is "prolate spheroid".
George Cooper Sr.: Wasn't looking for it, but thank you. Now, what do you think is the most efficient way to get this thing to fly?
Sheldon Cooper: Gyroscopic torque. Spiral.
George Cooper Sr.: Bingo. All right, now get your fingers on the laces here.
Sheldon Cooper: Why is the surface all bumpy?
George Cooper Sr.: Used to be made out of pig bladder.
[Sheldon retches in disgust]
George Cooper Sr.: Well, not anymore. It's... Helps with the grip, okay? Now, fingers back on it and get your thumb wrapped around. There you go. All right, bring your other hand up. That helps keep her steady. Bring the ball back to your ear and when you're ready to throw, bring your arm down like a tomahawk. Get that ball spinning, all right?
Sheldon Cooper: And am I correct in assuming that more revolutions will create a parabolic arc that resists external forces?
George Cooper Sr.: Sure. All right, whenever you're ready, let's see if you can reach me.
Sheldon Cooper: Let the setbacks and frustration begin.
George Cooper Sr.: [Sheldon throws a perfect pass to George] Good Lord! That was incredible!
Sheldon Cooper: Yeah. I saw it.
George Cooper Sr.: [Sheldon turns to leave] Where you going?
Sheldon Cooper: To hit the showers. Apparently, I'm a jock now.
