"Trivia" consists of a series of video segments that introduce and confirm the validity of unusual trivia. Past trivia has included exploding erasers, spiders affected by caffeine, and insects that cannot be killed. Most of the trivia on the show is sent in by viewers. A celebrity panel of five judges (ten in special episodes) evaluate each video segment and votes on how interesting it is by pushing a "hey!"-button every time they are astonished.
