Why was the guy with the half mask talking like Kathrine Hepburn first? Wouldn't it be better to normally sound like... I don't know... A man? Maybe I'm not smart enough to be a villianous henchman.
Actually, he was crazy. Crazy cartoon characters show they're crazy by acting like lethargic Jim Carrey's and doing bad impressions of celebrities kids don't know.
I'm pretty sure the last impression was Christian Slater. Or possibly Jack Nicholson. Or Luke Perry. Or some kind of Dennis Hopper.
