Doofenshmirtz Gives Perry A High-Five (animated)

Dr. Heinz Doofenshmirtz, excited over an apparent victory, tries to give Perry the Platypus (also known as "Steve") a high-five. Alas, their celebrating was short-lived, as the crazy Australian guy managed to escape Doof's trap (doesn't that always happen?). However, in this particular episode Doof really did save the day, and actually rescued Perry from certain doom.

This is taken from the Phineas and Ferb episode "Primal Perry".
