Tim Travers and the Time Traveler's Paradox

In 1998, Beavis and Butt-Head are sentenced to Space Camp by a “creative” judge. Their obsession with a docking simulator (huh huh) leads to a trip on the Space Shuttle, with predictably disastrous results. After going through a black hole, they re-emerge in our time, where they look for love, misuse iPhones, and are hunted by the Deep State. Spoiler: They don’t score.

Casper is a time traveller who arrives in the 2020s in an attempt to prevent a major future catastrophe. He meets Holly, a queer black woman he befriends and draws into his plan by giving her his knowledge of the future so that she can make quick money. However, they unwittingly alter the future themselves with their actions, until Doris, another time traveller, arrives to stop them.

After a high school lab experiment goes horribly wrong, Mordecai and Rigby must go back in time to battle an evil volleyball coach in order to save the universe — and their friendship.

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.
