Johnny Test
S04E19 Old School Johnny
Johnny finds himself transported back to the year 1845, where schooling is much simpler. However, he quickly realizes he can't return home as the necessary power source for the Turbo Time Tea house hasn't been developed yet. Alongside the sisters, Johnny embarks on a quest to discover obsolete technologies that could provide the energy needed to operate the tea house and help him get back to his own time.
