Phoebe: Oh, PBS.
Monica: What's wrong with PBS?
Phoebe: Oh, what's right with them?
Joey: Why don't you like PBS, Pheebs?
Phoebe: Because right after my Mom killed herself, I was just in this really bad place, personally. I just thought that it would make me feel better if I wrote to Sesame Street, because they were so nice when I was a little kid. No one ever wrote back.
Chandler: Well, you know, a lot of those Muppets don't have thumbs.
