MERRY CHRISTMAS!! From the SOS Brigade.
This is Haruhi's Christmas Day party. Haruhi and Kyon got done with delivering the presents Christmas Eve night. Link here: [link]
Sorry I have not seen The Disappearance of Haruhi Suzumiya movie yet. Waiting for the USA release copy. So I don't know what Christmas party in the movie looks like.
