Ep 1. The One With The Jellyfish

In Friends season 4 episode 1, titled "The One With The Jellyfish," the gang returns from their beach trip where Ross and Rachel have ended their relationship once again. As they all sit around in Monica's apartment trying to figure out what to do next, Joey suggests they play a game called "Strip Happy Days Game," where they remove an article of clothing every time someone gets a question wrong about the show Happy Days. This leads to some awkward and amusing moments.

Meanwhile, Ross is feeling the sting of regret after he and Rachel got into a fight and he drunkenly hooked up with another woman. When he tells Chandler and Joey about it, they try to help him come up with a plan to break the news to Rachel without upsetting her too much. But things get complicated when they discover Rachel had kissed another man during their break, and they argue over who was at fault.

As for Monica, she's dealing with some strange bumps on her hand that turn out to be caused by a jellyfish sting. She recruits Phoebe to pee on her hand, as she's heard that this will somehow alleviate the pain. The resulting scene is both hilarious and cringeworthy.

Throughout the episode, the friends grapple with issues of loyalty, trust, and communication in their relationships with each other. The dialogue is sharp and witty, and the performances are as strong as ever. Overall, "The One With The Jellyfish" is a great start to the fourth season of Friends, setting the stage for more antics and adventures to come.
