One day a squirrel ran by Phineas and Ferb's backyard. Phineas: Ferb! Look at that squirrel! The squirrel began to load nuts and ran up the tree Phineas and Ferb where under. * Phineas watches squirrel* "See how fast he gathers his nuts?" said Phineas "That must mean summer is ending and he wants to rest in fall"
