** The "[[Recap/TheSimpsonsS6E6TreehouseOfHorrorV Treehouse of Horror V]]" segment "Time and Punishment" has Homer repeatedly bouncing from his current time to the prehistoric era, and was told about the [[ButterflyOfDoom butterfly effect]] and its dangerous effects on the timeline. Even minor infractions such as accidentally killing one insect or animal lead to drastic changes. On his second visit to prehistoric times, Homer tries desperately to avoid touching ''anything'', seemingly succeeds and sits down in relief... on top of a lungfish. "Oh I wish, I wish I hadn't killed that fish!" Homer gets an even better one on his third visit, when he sneezes and inadvertently causes ''the extinction of the dinosaurs''. After that, all Homer can forlornly get out is "Thiiiiiiis is gonna cost me..."

After his (and Squidward's) attempts to make the jellyfish leave fail, [=SpongeBob=] finally has enough and tries to take the music player out of his house. He and the jellyfish get into a tug-of-war... Resulting in the music player shattering on the floor. [=SpongeBob=] can only look up and let out a little "gulp", as it sinks in what's about to happen to him as the jellyfish deliver their equivalent of a DeathGlare.
