Quote from Phoebe in The One with Joey's Porsche
Phoebe: Why are there only two of you? Where's Leslie? Well, you can't answer. Leslie? Where are you, Leslie? Now would be a good time for your first words. Well, look at you. You are a little bit mischievous. My gosh. Oh, you're a lot mischievous. Well, it'll dry. You sit with your brother and sister now ... who aren't there.
