Ep 5. World's Greatest Couple

In How I Met Your Mother season 2 episode 5, titled "World's Greatest Couple," the gang has a new couple obsession: Lily and Marshall. Ted, Robin, and Barney constantly fawn over how perfect they are as a couple, making the newly engaged pair uncomfortable with all the attention. To get some space, Lily and Marshall plan a weekend getaway to their bed and breakfast in New York's wine country.

Meanwhile, Ted and Barney start to argue about whether or not they could fake being a couple and win a bet at the bar. Robin tries to mediate their disagreement, but their competitive spirits get the best of them and they decide to give it a try.

Back at the bed and breakfast, Lily and Marshall's romantic weekend takes a turn when they are unknowingly booked in the honeymoon suite. To make matters worse, the other guests mistake them for a married couple and shower them with attention, including a massage and a private hot tub. Lily and Marshall try to politely decline, but their attempts only make things more awkward.

Ted and Barney's fake couple act doesn't go as planned, as they argue and compete with each other at every turn. Robin tries to keep them on track, but it all becomes too much when they end up kissing in front of their friends.

Ultimately, Lily and Marshall return from their weekend away feeling more in love than ever, despite the unwanted attention. Ted and Barney apologize to each other and Robin reminds them that it's not about winning, it's about being a good partner in a relationship.

"World's Greatest Couple" showcases the ups and downs of both new and long-term relationships, and how the pressure to be the perfect couple can sometimes be overwhelming. The episode also highlights the importance of communication and compromise in any partnership.
