Not Quite Forever

When someone says that something is forever, but it turns out it's not. Sometimes it is Lampshaded with "Forever is a long time." This is sometimes Played for Drama, and other times it's Fridge Logic.

This can range from how long a Sealed Evil in a Can stays in a can to how long best friends stay friends. It can also be used when breaking an oath that was supposed to last forever. Usually, before people realize Who Wants to Live Forever?, this applies. There are many times this trope can be applied.

Tethercat Principle is almost the exact opposite of this trope.

Music
"And when the feeling came upon me
 * Meat Loaf's "Paradise by the Dashboard Light:"

Like a tidal wave

I started swearing to my god and on my mother's grave

That I would love you to the end of time

I swore that I would love you to the end of time!

So now I'm praying for the end of time

To hurry up and arrive

Cause if I gotta spend another minute with you

I don't think that I can really survive"

 * Apparently expected by Homestar Runner when he is told he must stay with the demon in Strong Mad's creepy painting "for all eternity".

Cue a "One Eternity Later" card, and we see SpongeBob's and Squidward's skeletons sitting in the Krusty Krab.
 * The Simpsons:
 * Homer Simpson in the year 1974, to his cynical father: "No way, man! We're gonna keep on rockin' forever....forever....forever....[cut to 1996, and a suddenly "uncool" and morose older Homer] "forever....forever....forever...."

"Wuya: You didn't think I'd stay in that box forever, did you?
 * An episode of Animaniacs has Wakko essentially sell his soul to a Swedish-accented Death for a Swedish meatball (this being a parody of The Seventh Seal, which was a Swedish film). Death drags Wakko down to the netherworld with him, with Yakko and Dot in hot pursuit; once there, they find their brother reduced to a passive mind-slave who is forbidden to do literally anything, even talk (except when someone talks to him first). Yakko and Dot demand that Death set Wakko free - and he tells them that they will be reunited with their brother if they can beat him in a game of checkers. Well, they do - and Death then reveals that when he said Yakko and Dot would be reunited with their brother, he meant that they'd be imprisoned in the netherworld, too! Since they're now trapped for all eternity, the siblings refer to Death as their father and urge him to play with them; their pranks and annoying behavior drive him absolutely berserk. What really drives Death to the breaking point is when Yakko cheerfully says: "Just think, we get to be here forever and ever and ever and...." "Maybe I was a bit hasty," Death says, and he tells the kids they're free to go - for now. Someday they must return, but Death hopes that it won't be for a very long time!
