Minutemen
When three high-school friends invent a time-machine, they decide to use it to go back in time and prevent other youngsters from making humiliating mistakes.
What was a cunning plan from Lord Edmund Blackadder V to fake a time machine on his gullibly incompetent friends, turns out to be the real thing and hurls him and his imbecile underling, Baldrick, through the course of human history.
