On his US talk show, The Tonight Show Starring Jimmy Fallon, Jimmy stepped into the role of Will Smith as he performed altered rap lyrics to the theme tune of the 90s sitcom.
Jimmy roped in former stars of the show, Alfonso Ribeiro and DJ Jazzy Jeff, and it really was a trip down memory lane - we just wish Will could have been there too!
In the sequence, Jimmy is draped in colourful 90s gear and recreates the spinning throne scene, and graffiti on the walls. Before entering the studio, Jimmy raps: "'It's time to take The Tonight Show to sunny L.A.'"
And yes, Alfonso also performed the much-loved Carlton Dance!
I'm A Celebrity star Alfonso has still got the moves, and it doesn't come as too much of a surprise, as he stormed to victory as the winner of Dancing with the Stars in November last year.
Jimmy praised Alfonso on Twitter last night, saying: "You are the coolest. One take!!"
Comedian and host Jimmy told fans that the Fresh Prince sketch was in honour of his show being recorded in its former home in Los Angeles.
