While doing press abroad for his movie After Earth, Will Smith and his son (and co-star) Jaden Smith stopped by BBC One's "The Graham Norton Show." At the conclusion of the interview, Will and Jaden grabbed mics to put on a brief show for the audience.

While Will Smith beatboxed, Jaden treated the crowd to a short freestyle. Will followed in suit, rhyming: "Last time I was here, I did my 'Fresh Prince' rap / Eight million YouTube hits was on that / I can see your face, you like, 'What has he left?' / Well, this time I brought my DJ Jazzy Jeff!"

And with that, Jazzy Jeff and the Smiths performed a medley of Will's 2005 single "Switch," and DJ Jazzy Jeff and the Fresh Prince's ubiquitous "Fresh Prince of Bel-Air."

If that weren't enough, Alfonso Ribeiro, known for playing Carlton Banks on "The Fresh Prince of Bel-Air" TV show came on stage to do a number of trademark dances from the show.

Watch the performance below:
