Jack & Jack

Vine ingenues, YouTube megastars, hip-pop sensations, and best friends Jack & Jack bring their own brand of irreverent comedy, on-point style, and heartfelt life advice to You Don't Know Jacks. Nebraska natives Jack Gilinsky and Jack Johnson shot to instant fame after their first Vine, Nerd Vandals, was dubbed a perfect Vine by the Huffington Post. It's been looped more than ten million times since-and that Vine was just the beginning.
