We need more press runs from Will Smith. And, specifically, more appearances on late night TV.

Gearing up for the release of his new film, "Focus," the veteran actor and rapper appeared on "Late Show with David Letterman" on Wednesday, and he stole the show before his interview even started. As Will walked out on set, Paul Shaffer and The CBS Orchestra played "Gettin' Jiggy With It," which inspired him to grab the mic.

Greatness and nostalgia ensued.

The Fresh Prince has been getting his late night rap on all month, actually.

A few weeks back, he appeared on "The Tonight Show Starring Jimmy Fallon," where he and the host beat-boxed and then rapped "It Takes Two."

His recent inclination to grab the mic could suggest that maybe Will is itching to get back into the studio to work on a new album -- he hasn't released once since 2005's Lost and Found -- and it sounds like maybe that's the case.

“I went into the studio with Kanye," he said recently. "I’m thinking about it. I’m exploring. I’m not sure what I’m going to do yet but I’m exploring. I’m in a creative ceiling.”

"Gettin' Jiggy With It Part 2" on the way?
