Perry has been with OWCA since he was a baby, and he has been at the top of his game since day one. If he had a dollar for every time someone called him OWCA's best agent, the Flynn-Fletchers would never have to work a day in their lives. Which is why he can't believe his ears when Major Monogram assigns him to Dr. Heinz fucking Doofenshmirtz. Perry may just be a platypus, but that doesn't mean he has to sit there and take everyone's bullshit, and he's going to make sure everyone knows it.
