Dr. Heinz Doofenshmirtz may have been an evil scientist, but that didn’t stop him from asking valid questions. Now that it’s out there, we can’t stop thinking about it either. Why do we always see cow skulls in the desert? It’s not like the desert is their natural habitat, so how did the skull end up there?

More importantly, why is it just the skull, not the entire body? The plot thickens. We don’t have all the answers, but maybe Perry the Platypus, also known as Agent P, knows the deal. After all, he is a secret agent for the O.W.C.A. (The Organization Without a Cool Acronym).
