*NSYNC's comeback was even more ephemeral than any of us predicted: Not even a full song, just enough of "Bye Bye Bye" to get J.C. Chasez in front of the Popping and Locking Triangle for a few bars. As it turns out, it was enough--people got their chance to gawk at their childhood in 720p (or on a crappy YouTube video of someone's TV, if they missed it.) Thus sated, they resumed being scandalized by Miley Cyrus, or maybe by having created Miley Cyrus.
But where does the rest of *NSYNC go when Justin Timberlake goes back to being Justin Timberlake? We've done the research, momentarily, so that you don't have to.
