Also, between the shots before Phineas falls, her sash disappears, reappears and then disappears again. It reappears after Phineas falls, and Isabella says, "Quick, everyone! Sashes!"

Continuity mistake: In the scene where Doofensmirtz talks about how the sign blocks his view of other people's pain and misery, his window faces the sign.
