Justin Timberlake has taken his "Dick in a Box" video one step further, onto the New York stage!

His Saturday Night Live partner in crime Andy Samberg joined him onstage the other night during Timberlake's Madison Square Garden performance. They both had wrapped boxes on their genitals and sang the song. There also seems to be a third person who has a box on his, um, dick. Maybe he's singing part of the song? Did Samberg sing the original song with Timberlake or just mouth the words?

Here's the video at College Humor. It's a bit shaky and you can't hear the song incredibly well over the screaming fans, but you get the idea.
