A little more than 20 years ago, the pint-sized hip-hop duo Kris Kross implored us to 'Jump.' They also wore all of their clothing backwards and shaved patterns into their eyebrows. Yup, it was the '90s.

Chris Kelly and Chris Smith, aka "The Mac Daddy" and "The Daddy Mac," did have some success after 'Jump' dominated the airwaves in 1992. However, when their gimmick of wearing their clothing differently than the rest of the human race wore thin, they fell from the public's eye.

Now they're reuniting for a 20th anniversary all-star concert honoring So So Def Recordings. The event will be held in Atlanta next month.

Will the fellows take to the stage with their buttons and zippers on their back? That's obviously the question on everyone's mind. See Kris Kross in their younger days, in all their leaping glory, below.
