Dick: Step right up, kids, and meet the girls of physics. Each and every one of them a bundle of mass and energy.
Boy #1: Are you really a licensed bikini inspector?
Dick: Uh, kind of. I'm a physics professor, you understand? Now, friends, let me tell you about a little thing called physics. You know what makes a car go fast? Physics. And you know what makes a curve ball curve? Why, physics! And you know what's got me standing here instead of floating out the window like a puff of smoke? Inertia, with a capital "I." That rhymes with pi, and that starts with "p," and that stands for physics.
