[A single celled organism, resembling Lincoln appears.]
S.C. Lincoln: Huh?
[He then separates into a lot of cells and eventually turns into a jellyfish and then into a fish-like creature.]
Fish Lincoln: [narrowly avoiding a octopus Lori] Aah!
[The organism then swims onto land, growing legs and turning into an amphibian that eats a dragon-fly like Rusty. He then turns into a dimetrodon as he sees dinosaurs and a pterodactyl resembling Scoots.]
Scoot-adactyl: [screeches]
[Then, Lincoln turns into a rat, while a tyrannsosaurus rex resembling Lana sneaks up behind him.]
T-Lana: [roars loudly]
[While chasing Rat-Linc, T-Lana ends up getting hit in the jaw by a stegosaurus resembling Lola. The two then get in a fight cloud, which lets Rat-Linc escape into a hole. Suddenly, meteors are seen in the sky and crash onto the surface, killing all the prehistoric creatures up above. Rat-Linc then jumps out the hole, past a T-Lana fossil and turns into a monkey.]
Monkey Lincoln: [makes monkey noises while climbing vines, then turning into an ape]
[Ape-Linc lands on the ground and turns into a caveman version of Lincoln, who then walks through a snowstorm and passes a caveman Chandler.]
Chand-man: Hey, Larry!
Cave-Linc: Lincoln!
[Caveman Chandler walks in the other direction, devolving into a rat. Caveman Lincoln then evolves into an Arthurian villager, a conquistador, then a pilgrim, then a Victorian Era gentleman, and eventually becomes the modern day Lincoln. He walks over a sleeping Charles, opens the front door, and sits on the couch with the other siblings.]
Lori: What took you so long, Lincoln?
Lincoln: I went through the full cycle of evolution to get here, guys.
Lisa: Fascinating...
