Phineas and Ferb were sitting in their backyard one hot sunny day. It had rained the night before, and so the worms were dislodging themselves from the ground. A bluejay swooped down upon one, squawking and startling Phineas and Ferb. "Hmm. It's funny how birds go after worms," said Phineas. "It's one of those pairings that everyone knows." Along with Phinabella, thought Ferb, smirking slightly. "Why do birds go after worms, anyway?" Phineas wondered aloud. "It's the food chain, Phineas. Let's not go building any machines that disrupt that. It could tear apart the very fabric of time!" "No, it won't." "That was hyperbole."
