Nastoletni geniusze Sezon 2 Odcinek 6: The Great Dork

When Russ is bullied by Garth, Toby tries to prove Russ is not a loser. Toby creates a time portal to show Russ his ancient, valiant ancestors. But things go horribly wrong. The time machine is damaged and Russ finds that he's swapped places with his 350,000-year-old hominid ancestor, Rog. While the caveman battles with Garth at a twenty-first century school, Russ is hailed as leader of a tribe of cave-dwelling hunter-gatherers. Eventually, Toby repairs the time machine and Russ, the inventor of the 'Cro-magnon pizza', returns to present day more confident and assured but Toby and Sacha are exhausted after a day of minding a donut loving Rog.
