LOL Video: Will Smith, Alfonso Ribeiro Reunite for Fresh Prince Theme, Carlton's 'Unusual' Dance

Now this is a story all about how… Will Smith revisited his Fresh Prince of Bel Air roots on The Graham Norton Show this week, bringing two special friends along for the ride down memory lane.

Appearing on the BBC talker with son Jaden to promote their father-son space movie After Earth, Smith grabbed a mic, introduced longtime collaborator DJ Jazzy Jeff and launched into a sing-along-with-me reprise of the Fresh Prince theme. UPDATE: Apparently this was a follow-up to Smith’s year-ago appearance on Graham Norton (seen here).

Smith then segued (at the 3:45 mark) straight into Tom Jones’ “It’s Not Unusual,” setting the stage for onetime cast mate Alfonso Ribeiro‘s cameo, doing a full-on, take-no-prisoners rendition of The Carlton, his Fresh Prince alter ego’s spastic dance perhaps only rivaled on TV by The Elaine.
