While Will Smith didn’t seem happy during the face smacking incident, he looks all sorts of gleeful relieving his past by rapping The Fresh Prince of Bel-Air theme song.

While promoting Men in Black III in the U.K., Smith got the whole crowd singing along with him. The only person who doesn’t seem to know the words is fellow guest Tom Jones. Yes, the same Tom Jones that sings Carlton’s favourite song, “It’s not Unsual.” Awkward.
