Quote from Joey in The One Where Everybody Finds Out
Phoebe: You don't have to do anything. Just don't tell them we know. Joey: No. I can't take anymore secrets. I got your secrets, I got their secrets, I got secrets of my own, you know. Rachel: You don't have any secrets. Joey: Oh, yeah? Well, you don't know about Hugsy, my bedtime penguin pal.
