Quote from Phoebe in The One Where Everybody Finds Out
Phoebe: So they know you know, and they don't know that Rachel knows? Joey: Yes, but you know what, it doesn't matter who knows what. Now enough of us know that we could just tell them we know. Now, all the lying and the secrets will finally be over. Phoebe: Or, we could not tell them we know, and have a little fun of our own. Rachel: What do you mean? Phoebe: Well, you know, every time they say they are doing laundry, we'll just give them a bunch of laundry to do. Rachel: Oh, I would enjoy that.
