I must confess, I've never heard of Mr. Wizard

From iwatchstuff, Don Herbert, the former children's TV science host better known as Mr. Wizard, died this morning after a long battle with an evil, more powerful wizard.

Just kidding! As usual, it was cancer that beat science once again. It's really a sad loss for the kid's science television show community, which will now have to hand over leadership to the slightly more obnoxious Bill Nye or the vastly more obnoxious Beakman.
