Favourite Christmas Episodes?

It depends what you mean by Xmas episode. There was usually an episode per season where Xmas or New Year is involved.

Season 1 - the Monkey episode where they have a New Year party with a 'no date' pact but everyone ends up with one. This is when the radiator is broken and the apartment is really hot.

Season 2 - Phoebe's Dad episode, Chandler and Joey end up buying terrible gifts from a gas station because they didn't have time to shop properly because of her visiting her Dad.

Season 3 - The One where Rachel Quits, so this is the main story and Ross selling cookies for a girl he hurt is the other story, but there is also the sideline where Joey is selling Xmas trees and Phoebe acts like a dick about it.

Season 4 - Girlfriend from Poughkeepsie has the bit where Phoebe writes a holiday song about the gang.

Season 5 - Not really too much but in the Inappropriate Sister episode, Phoebe rings a bell for donations outside Macy's.

Season 6 - This is the routine episode, New Year related but obviously the New Year party show is pre recorded. But Rachel, Phoebe and Chandler are looking for Xmas presents while Monica is out doing the routine, so a vague Xmas theme.

Season 7 - actually has two, because you have the Armadillo episode and also the one where Monica makes candy.

Season 8 - the episode where Mona wants her and Ross to send out a holiday card together.

Season 9 - Chandler is stuck in Tulsa for Xmas, he quits his job so he can come home to Monica .

Season 10 - doesn't seem to be one.
