Dib Membrane's horrible, yet rather sexy father from the early 2000s nickelodeon cartoon 'Invader Zim'. Professor Membrane is a 12 foot (at least) tall world-famous scientist, who neglects his kids, but on the bright side he has incedibly hot robotic arms after losing his fleshy ones to sharks. He is a DILF.
