PSY's "Gangnam Style" has gone the way of Carly Rae Jepsen, inspiring a number of copycat and tribute videos on YouTube.

And today, two more have gone viral.

While PSY's original video was a fun, dance-filled affair, "The Sing-Off" winners Pentatonix offer up an impressive a cappella version of the song with only a few moves.

In another corner is a video squarely focused on dancing.

The inmates at Cebu Provincial Detention and Rehabilitation Center in the Philippines are at it again, trading their "Thriller" moves for PSY's now-trademark gyrations.

One version of the video, which was uploaded over the weekend, already has over 1 million hits ... and the numbers keep rising!

Check out both videos above. Which is your favorite?
