8. The One with the Routine (Series 6, Episode 10)
The later seasons get a lot of stick but, as my favourite character is Ross, this particular episode only serves as another great example of how the Gellar family are complete screw-ups. We are told regularly how strange their upbringing was but, considering how specific this routine needed to be, Schwimmer and Cox must’ve prepared for weeks to get it right. Ross as wet-blanket is great in the first few series as Schwimmer can play it so well. But Ross as manically-depressed and a bit nuts is when he truly comes out of his shell. Considering the cast, towards the end, were rumoured to be paid $1m per episode, they surely had to work hard for this one.
