Will Smith is feeling crazy inspired these days -- a new YouTube channel, a new National Geographic series, a new movie with Ang Lee, a new Instagram following -- and he promoted it all on "The Tonight Show Starring Jimmy Fallon."

But he'll always be The Fresh Prince, and he hasn't forgotten those roots. Nostalgia TV is hotter than ever, and Smith and Fallon honored some of the best TV sitcom theme songs of all time in a special live remix.

Here's the list of TV show songs they covered:

  • "The Golden Girls"
  • "The Jeffersons"
  • "Diff'rent Strokes"
  • "Good Times"
  • "The Andy Griffith Show"
  • "I Dream of Jeannie"
  • "Full House"
  • "The Greatest American Hero"
  • "Martin"
  • "Three's Company"
  • "The Fresh Prince of Bel-Air"

Check it out:Smith promoted his new YouTube channel by doing a drone interview, so here's that: Smith also promoted his 10-part National Geographic series, "One Strange Rock," directed by Darren Aronofsky: Good for him for still being inspired to try new stuff. He could easily just coast on doing the same things -- or nothing at all.

"One Strange Rock" premieres Monday, March 26 at 10 p.m. on Nat Geo.
