Man on Subway Rocks out To Rihanna

This is HILARIOUS! The guy with the sunglasses on rocking to cool denim jacket is just straight singing his heart out to Drake and Rihanna's 'Take Care' and it's so funny. This guy get's down singing some Rihanna, he's got his runs, vibratos, and any other singing term you can think of down pat! I'm thinking that maybe since he has his headphones in he has forgotten that when he sings out, everyone can hear him.Also I'm not really sure what's funnier, the guy actually singing the song or the guy in the front who's a very clean cut business looking man, who is looking at a newspaper and trying his hardest not to crack up.
