Quote from Phoebe in The One After the Superbowl (Part 2)
Rachel: Would you let me talk. Monica: Did you just flick me? Rachel: Well, you wouldn't let me finish and I was- Ow, that hurt! Monica: Quit flicking! Rachel: You stop flicking! Monica: You flicked me first. [Monica and Rachel start hitting each other] Phoebe: Oh. Let's not do this. Happy thoughts. Happy thoughts. [Monica gets Rachel to the ground, removes her sock and starts hitting her with it] Phoebe: Okay, now I'm gonna kick some ass! [Phoebe grabs Monica and Rachel by their ears] All right. Now, I will let go if you both stop.
