Quote from Diane in One Last Fling
Sam: Uh, excuse me, uh... When do my, uh, 24 hours begin? Diane: Right now. Sam: All right. Diane: The same as mine. Sam: Okay. Wait, wait, whoa, whoa, whoa! Yours? Diane: Of course, Sam. This is the only way we can be sure that I have all other men out of my system.
