Quote from Chandler in The One Where Estelle Dies
Phoebe: Well, we cannot tell Joey about this. He's already flipping out about everything that's changing. This will push him over the edge. Monica: Seriously, you don't think we should tell him? Phoebe: Well, not for a little while. Let's just give him a few days to get used to everything else. Monica: What if he reads it in the paper? Chandler: Unless Snoopy says it to Charlie Brown, I think we're okay.
