For this purposes of this blog and my sanity, I am only acknowledging the first two Chrismukkah episodes. I know there are four. I don’t care. 
The first Chrismukkah introduced the concept of the bi-religious holiday but the second one perfected it. In season one of The O.C., Ryan is still going hard after the title of Broodiest Boy in all of California. He had a HORRIBLE first Chrismukkah. I prefer the second one. He’s happier and he’s with Lindsey who has NEVER been arrested at the mall. Although for the record that’s not how mall security would deal with shoplifting.
In season two, Ryan tries hard to keep Chrismukkah contained but it spills over and ruins multiple lives. His heart was in the right place, of course, how was he to know he was dating his adopted grandfather’s illegitimate love child? What are the holidays for if not exposing family secrets?Although Lindsey telling Ryan her sad Christmas story without a hint of irony is atrocious. As if one year away from Chino means he suddenly loves all December holidays.
Season one Seth and Summer are still dealing with Anna the Interloper (I don’t have a problem with Anna but we all know she doesn’t belong in The O.C., the county or the show) and he makes them each Seth Cohen Starter Packs. They return the thoughtful gifts and he gives them to his parents because one can never have too many copies of The Goonies. 
Summer became one of my favourite characters mostly because of Rachel Bilson. She’s feisty and smart and much more compassionate and intuitive than she’s originally portrayed as. In season two she saves Chrismukkah for completely unselfish reasons. She has a couple nice moments with Seth even though they are broken up and both seeing other people. She’ll always be too good for him, full offence Cohen. 
Season one Marissa is obviously going through something and she’s not going to get better for a very long time. And then well… we all know what happens in season three. In Ryan’s defense though that car door slamming scene was cathartic. She’s being an absolute terror and he deserves better. At the end she finally goes to therapy and we get the first appearance of Oliver! Is he even in therapy? We already know he’s a batshit crazy liar. I bet he’s just there scamming on damaged girls like Marissa. He’s so gross and slimy already, I hate him out of the gate. 
Season two Marissa has calmed down and is kind of boring. Her parents are having a ridiculous affair and she still manages to make the Chrismukkah drama about her by announcing, “My ex-boyfriend is dating my step-sister,” yeah, so? No one cares about you, shut up.
Also the indie band Christmas tunes in these episodes are fantastic. I highly recommend The O.C. Mix 3: Have a Very Merry Chrismukkah for your upcoming non-denominational holiday parties.
