Say a movie-quote (nothing randomly obscure!).

Next person guesses the movie and states their own quote.

"Once upon this same earth, beneath this same sun, long before you, before the ape and the elephant, as well; before the wolf, the bison, the whale, before the mammoth and the mastodon, in the time of the dinosaurs. Now the dinosaurs were of two kinds. Some had flat teeth, and ate the leaves of trees, and some had sharp teeth for eating meat, and they preyed upon the leaf-eaters. Then it happened that the trees began to die. The mighty beasts who appeared to rule the earth, were, in truth, ruled by the leaf. Desperate for food, some of the dinosaur herds struck out to the west, in search of the Great Valley, a land still lush and green. It was a journey toward life."
