The nostalgia of this one! How dope! Last night, Will Smith was the guest on David Letterman’s late night spot, and along with the show’s in-house band, he performed his 1998 smash single, “Gettin Jiggy Wit It.” Perfect for TBT, huh? David also learned (via Will) that there’s a black man inside of him. Whet? LOL! Watch the funny clip below.
