Dr. Doofenshmirtz, that dude was a friggin genius. He invented a magnet to attract wood (using it to destroy a beaver dam, flood the worlds oceans, raising the sea level by 2 and a half feet, to make his condominium valuable beachfront property), a laser that could instantly destroy anyone who cant make up their mind (admittedly it was probably just a normal laser), invented a laser that could turn anything into bread, and waved a giant magnet around his ex girlfriends house to erase some embarrising phone messages he left on her answering machine. He even stole all the lawn gnomes out of 3 states in order to exact revenge on his father.
Although his best plan was undoubtedly when he stole all the worlds tinfoil, covered the western seaboard in tinfoil, and then threatened to use a giant magnet to pull the western seaboard across the united states and reverse the rotation of the earth. Now THAT's an evil plan.
Unfortunatey, I cant find any good clips of the guy in rare form (aka when he describes his best inventions, so I was stuck with one of his more normal ones
BTW: YES I know the show is on the Disney channel, I found this guy flipping through the channels one day. Now, I tune in to the show whenever its on just to hear Dr. Heintz D. Doofenshrmirtz's hillarious schemes
