Will Smith Raps The Fresh Prince Theme On Graham Norton!

We never thought this day would come, but here it is!
Will Smith is busy promoting his new movie, Men In Black 3, all over Europe, but during his appearance on The Graham Norton Show last night, it quickly became all about the show on which the actor got his start back in the day, The Fresh Prince Of Bel Air, and suddenly, it happened!
He RAPPED THE ENTIRE THEME SONG along with the entire audience!
Oh, and it happened to be with Gary Barlow!
Seriously, no words can describe it!
Please, please watch this moment of true greatness (above at the 1:10 mark)!
