Will Smith Enthusiastically Rapped the Fresh Prince Theme Song For Ellen

Eternally the good sport, Will Smith appeared on The Ellen DeGeneres Show and rapped the lyrics to The Fresh Prince of Bel-Air's theme song. He's making the rounds promoting Focus, and since he rapped "Gettin' Jiggy Wit It" on Late Show With David Letterman last week, he's presumably looking to top himself every time he's in public. What else can he do? Will he enlist Kevin Klein for a rendition of "Wild Wild West" for Jimmy Kimmel on Wednesday? Fingers crossed.
