There could only be one, and you might have guessed it from the get-go. Season 5 of "Friends" has so many highs, and very few lows, making it the only season worthy of the top spot on our list. The beginning of the season saw Monica and Chandler hide their relationship from their friends, which birthed many hilarious episodes. "The One Where Everybody Finds Out" is regarded as one of the best episodes in the series, as Chandler and Phoebe test one another limits.
We could have done without the "Rachel smoking" and "Joey's bag" subplots, but every season can't be absolute perfection. Think of everything else Season 5 gave us: PIVOT!, Mrs. Ross and Mr. Rachel, Ross's leather pants, the birth of the triplets, "The One With All the Kissing," Ross's sandwich, and Phoebe's hatred of PBS. There are just too many incredible moments to choose from, and Season 5 showed the best the six characters had to offer as the cast couldn't have perfected their roles anymore at that point.
- Worst Episodes: "The One With Joey's Bag," "The One With Chandler's Work Laugh," "The One Where Rachel Smokes"
