The Filthy Critic's review of Run,Lola,Run at:

http://www.bigempire.com/filthy/runlolarun.html

he writes the following:

It's like that freaky story by Ray Bradbury where that guy goes back
to the time of dinosaurs and kills a butterfly. And when he gets back
to the present, he discovers that killing one butterfly forever
altered the world.

What is the name of this freaky story and where can i find it?

Very comprehensive answer. I also remember the Simpsons making that
reference to the story.

A pterodactyl flies overhead, and Homer begins to panic.

Homer: Aah!  OK, don't panic -- remember the advice your father gave you
       on your wedding day.
        [remembers Abe with hair and a tuxedo]
  Abe: If you ever travel back in time, don't step on anything because
       even the tiniest change can alter the future in ways you can't
       imagine.
Homer: Fine.  As long as I stand perfectly still and don't touch
       anything, I won't destroy the future.
        [a mosquito flies in]
       Stupid bug!  You go squish now!  [swats it]
-- Touching and swatting are different, "Treehouse of Horror V"

Homer realizes what he's done.  "But that was just one little
insignificant mosquito.  That can't change the future, right?  Right?"
he asks a passing bearlike creature, who shrugs and grunts "I dunno."
The toast pops and Homer finds himself back in his basement.
