So Jen has destroyed what little of a mind I had left, and I can't stop listening to Captain Jack... but somehow ALL I CAN THINK OF is Chris Pine and Zachary Quinto doing the Shoulda Put A Ring on it dance, but to Only You. I swear to god, if I could make a GIF of it, I would. And actually, I MIGHT BE ABLE TO. I just gotta re-upload Flash onto my computer...
Presumably the result will be something like this.

Seriously, put on the
video, turn off the sound and play
Only You instead, because they go PERFECT together, kind of the weird way that A Happening by Hyperstory goes perfect over the Silent Hill 4 opening scene... Then imagine Chris and Zach and Karl dancing in leotards, kinda like when Justin Timberlake did it on SNL.
There's only a couple second delay, but I think it works vastly better if you turn the song on first so that they step forward when the girl starts singing. The song should be at about 1 to 2 seconds by the time you click play. And yeah, the match is so perfect that 3 or 4 seconds into the song won't be nearly as good, nor would somehow starting them simultaneously.
I've watched it like 17 times now....
