Will Smith has been giving us quite a few cases of nostalgia during his media run for his new movie Focus, and if anyone loves enforcing nostalgia moments, it’s Ellen DeGeneres.

As he sat down with the comedic talk show host, Will got up out of his seat, and sang the theme song to his 90’s breakthrough sitcom The Fresh Prince Of Bel-Air.

The actor made sure to test people’s knowledge of the lyrics, and had the audience sing along to the famous song with him.

This comes on the heels of another epic throwback performance from Will, as he performed “Gettin’ Jiggy With It” on David Letterman’s show last week.
