Looking like just got done hanging out with DJ Jazzy Jeff and the Fresh Prince, meet awkward subway-singing guy. He really likes Rihanna. And he's all about taking care of you.

My favorite has to be the guy in the suit making the most pained trying-not-to laugh face ever. Or when Mr. Rihanna himself doesn't really know the words at the end and just keeps repeating "I've loved and I've lost"... or his wicked awesome vibrato, I really enjoy that too.

What would you do if you got stuck in a public transportation vehicle with someone this into singing out loud? I think I might just join in. Or a bust a move. Wait no, I'd do what the guy with the camera did and just start filming.
