Dr. Doofenshmirtz:
Yeah, I had to place myself in restraints. There's a perfectly good explanation, though. It all started a couple of days ago when I declared war on grass. It's-it's not important WHY, exactly. L-let's just say grass got on my bad side. Grass and me, we're on the outs, big time, so I got myself a cow - the natural predator of grass. It was slow going. What I needed was a cow that was motivated not by hunger but by a powerful hatred of grass, like... like my own burning antipathy, so I invented the Mind-Transfer-inator to give that cow a piece of my mind. And, as it turns out, cow brain... not a lot of room in there for new ideas.
