Back From The Future

=Episode Plot=thumb|300px|right

Sandy has invented a time machine and shows it to SpongeBob. Squidward overhears, and uses it to travel back in time to when he fell down the stairs (from the episode Squidward's "Dream" of SpongeBob), in attempt to stop that from happening.

Once in the past, Squidward finds his past self fainting from the sight of the three different SpongeBobs. He orders them to use the "Breath of life" to revive his past self, something of which the small SpongeBob finds disgusting, and suggests that they just leave past Squidward unconscious. However, it is eventually "agreed" that the Superhero SpongeBob will revive past Squidward, and he does.

Future Squidward falls of the bed and encounters Lisa Simpson, knowing that his past self will encounter her soon, he tells her to tell his past self not to go down the stairs. Lisa is confused, but agrees to do so nevertheless

When past Squidward sees Lisa, he tells her that "she doesn't belong here" (as she is the only toy in the room that has nothing to do with SpongeBob). Past Squidward freaks out and runs off, Lisa tells him not to go, but it is too late, and past Squidward has already fallen down the stairs.

When future Squidward asks SpongeBob and Patrick to take care of his past self, they tell him that Squidward's time travelling may have inadvertently been what caused him to fall down the stairs in the first place. Upon hearing this, Squidward realises that they may be right, and bangs his head in anger and frustration. In the process of this, he himself manages to accidentally fall down the stairs.
