Looking For A Smile? – Watch This Guy Sing ‘No Diggity’ At Airport

Sitting in an airport waiting for your plane is probably on most people's list of things that they don't enjoy doing.  So, when a guy gets up and grabs the intercom at the gate to sing an acapella version of Blackstreet's 'No Diggity', it's understandable that the crowd would go wild.

The reason why he was singing was because the gate attendants made a rule that anyone who came up to ask a question, had to sing a song on the intercom.  Well, that rule was totally embraced by the man in the video.  What song would you sing if you HAD to sing one in front of a crowded airport terminal?
