//Talking about jerk (3rd derivative of position) in analysis
Rose: So I guess you could take fourth and fifth derivatives of position, but that's not really helpful. Maybe you'd want to know how fast you're..jerking...
Rose (realizing what he said): Oh, I went there.
Rose: So we just took the derivative. Taking the derivative is like sex. The hard part is simplifying the derivative, which is like pillow talk.
//Later, Rose and Paul are simplifying a long derivative together
Rose: This is some of the best pillow talk I've ever had.
