Quote from Monica in The One with Rachel's Other Sister
Monica: I wanna have a kid with you because I think you'll be an amazing dad. At the fun parts and at the hard parts. Chandler: Yeah. Well, can you picture me saying, "Go to your room, you're grounded"? Monica: Can you hear me say, "You're grounded"? Chandler: You said that to me last week. Monica: How hard is it? "No shoes on the furniture!"
