Quote from Robin in The Pre-Nup
Marshall: Okay, you know what? Since we're all pitching in, may I suggest a provision? In the event that you have a son, Mr. Stinson is free to play with his child however he sees fit. Lily: How about forbidding your future husband from spiking his child into his crib? Nick: How about a clause protecting you from having to engage in a three-way with her and whatever's on basic cable? Robin: Oh, yeah? How about forbidding... I got nothing.
