On the most recent episode of "Lip Sync Battle," Anthony Mackie came out strong with an MC Hammer performance. Needless to say, he was "2 Legit 2 Quit." But he was absolutely crushed by Joseph Gordon-Levitt's performance of "Rhythm Nation" by Janet Jackson. The look on Mackie's and LL Cool J's faces say it all.
Seriously, though. Watch Jackson's original music video. JGL did it perfectly.
