Mr. Wizard hosted a television show back in the day, teaching kids lessons about science and other boring crap.  I remember watching the show on Nickelodeon back in the 80's, but I don't remember Mr. Wizard being such a dick.

Don't get me wrong, if I dealt with stupid ass kids all day, I would probably act the same way, but that's why I work for the Banana and not Nickelodeon.  Mr. Wizard was on the air back in the 50's and 60's and made his return to TV in the 80's.
