Blackadder: Back & Forth (1999)

The final episode in the saga of the Blackadder family, who have forever been at the very center of British history and society.

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.
