Quote from Will in The Philadelphia Story
Vy: Hold it, hold it, hold it. I'm putting both of you right out here on the convertible couch. And Ashley and Hilary will be with me. Philip and Vivian will have your room. Will: Hey, Mom, listen, you should probably make sure that Uncle Phil sleeps on the bottom bunk. Because if he get up on the top bunk... Well, you know gravity ain't no joke. You know what I'm saying? He could end up in China.
