(Scene opens up with Phineas and Ferb playing with remote-controlled cars.) Linda: Hey, boys. Phineas: Hey, Mom! Linda: What are you up to today? Phineas: We're racing our remote-controlled monster trucks. (Remotes clicking) Linda: I don't see any monster trucks. Phineas: Oh, that's 'cause we rigged them to go light-speed. You how those stock motors are. They never give you enough action. Linda: (oblivious) You boys have such active imaginations. You must get it from your father.
