We had a Warehouse 13 Christmas episode. Same with Eureka. Did nobody think of the potential of a Stargate Universe episode--Christmas in space? (Say that slowly. Like, "Christmas! IIINNNNNNNNN...SPAAAACCCEEE!)

It would have been neat to see the crew get all homesick when someone realizes what day it is. There could be sheepishly-made gifts, some improv mistletoe, and they would bring a tree aboard from another planet and that is when the trouble starts. Some sort of parasite (like we haven't seen that before, heh) or alien is in it. Also, Rush would definitely be a Grinch/Scrooge character.
