"The One Where Phoebe Hates PBS" is the fourth episode of the fifth season of Friends, which aired on October 15, 1998.
Rachel goes into Monica's bedroom to bring her some mail and comes out screaming over the position she found Monica waiting in on her bed. Monica reveals that she has a secret boyfriend and claims it's a guy from work. Joey and Ross also show up and, a short while later, Chandler enters with a bottle of champagne. Upon seeing everyone there, he claims he wants to celebrate the fact that his office finally got wrinkle-free fax-paper. Rachel, unaware that the secret boyfriend is Chandler, asks Chandler if Monica has mentioned him and reveals that Monica told her that this guy is best sex she's ever had. Chandler is delighted with this news and goes overboard in his gloating. This annoys Monica, who threatens to cut Chandler off until he apologizes and tells her that, if he's the best, it's only because of her. He says that he was nothing before her, but when he's with her "Oh. My. God."
Joey wears a tuxedo believing he's hired as host for a PBS telethon, but is actually just hired as one of many phone operators on screen, even sitting outside the main camera view. Phoebe says she hates PBS because it reminds her of the miserable days when her mother watched Sesame Street on it before committing suicide and even complains that Joey's telethon is selfishness masquerading as a good deed; when he retorts that having the babies also wasn't a selfless good deed because that doesn't exists, she promises to prove there is. Because she fails at all her attempts, she decides to donate $200 to PBS, because "they bring happiness to lots of kids whose moms didn't kill themselves", and she won the bet. However, this donations leads to Joey being the volunteer which broke last year's record, so he finally gets on TV; which makes Phoebe happy.
Ross tries to make up with Emily by phone, but is asked to move to London, which he can't do because then he can't see his son Ben anymore, and he also can't convince Carol and Susan to move to London. When Emily finally agress to move to New York to work on their relationship there is one problem: she wants Ross to agree that he won't see Rachel anymore, which the others consider totally unreasonable. Because nobody, including Ross, has an idea how to solve this, he became desperate enough to leave the decision to a Magic 8 ball, which proves uncooperative. Not knowing about the condition, Rachel incites Ross to do whatever Emily wants, which he does.
