Quote from Phoebe in The One After Vegas
Joey: Pheebs, look, I am so sorry. I know I promised you a fun road trip with your friend and I didn't deliver, okay? But now I know that you think being awake is an important part of friendship. So I will strive to stay awake for as long as I know you. Phoebe: You can still, like, sleep at night and stuff. Joey: Thank you.
