He’ll Take Care of You– Dude Belts out Rihanna on the Subway
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.
