This is a short video of clips from Star Trek: The Next Generation edited together so the cast sings 'Let It Snow' (technically, 'Make It So'). At least that's what the first half of the video is. The second half is the guy who edited it talking about a video game he's developing. Admittedly, not a bad tactic to get the first, unrelated half of your video game video watched.
Hit the jump for the video.
