Timberlake was seducing the audience from his perch behind an upright piano—which, skeptics take note, he actually played—bouncing and winking and generally having his way with everyone in the room. Then, for no comprehensible reason, he grabbed a camcorder, held it up to his face and serenaded himself Blair Witch Style. There's an obvious sexual metaphor here, but I'm far too modest to explain it. Let's just say it was an unfortunate end to what was on course to be the best performance of the night.
