I don't see these on the list in the first post, so - all of these are <i>Grey's Anatomy</i> and available in The Complete Second Season Uncut box set:
-- For Thanksgiving, "Thanks For the Memories"
-- For Christmas, "Grandma Got Run Over By a Reindeer"
-- For New Year's, "Begin the Begin"
Also, though they are a year away from DVD release, by the time someone views this thread for next year, the following will be out on DVD:
from <i>Ugly Betty</i> Season 1:
Halloween - "The Lyin', the Watch and the Wardrobe"
Thanksgiving - "Four Thanksgivings and a Funeral"
Christmas - two episodes: "Fake Plastic Snow," the proper Christmas episode, and also Fey's Sleigh Ride, which aired in October but features the magazine prepping their Christmas issue.
from <i>Brothers & Sisters</i> Season 1:
Thanksgiving - "Mistakes Were Made, Part II"
Christmas/Hannakkah (both) - "Light the Lights"
from <i>Desperate Housewives</i> Season 3:
Christmas - "The Miracle Song"
And I have a very cool VHS release from 1995 of "Yogi Bear's All-Star Comedy Christmas Caper," which is a lot of fun but is no longer available and isn't on DVD. If you can manage to track it down, it's a cute little special. I wonder why it's not shown on TV during the season. In it, several of the other Hanna-Barbara characters go to Jellystone Park to celebrate Christmas with Yogi, but he goes to the city to celebrate with them, ends up impersonating a mall Santa and meeting a cute little girl. As far as I know it's not on DVD -- IMDb doesn't even have it listed -- but I thought it would at least be worth a mention here. It is one of the very few things I actulally go back to watching VHS for so that I can see it every year on a yearly basis. It might be on the Yogi Bear Complete Series DVD, but I'm not sure. In any case, here's a link to the VHS on Amazon:
