Hey, kids. Mr. Wizard is way smarter than you – and he’ll let you know it. Over and over again.

Children of the ‘70s, ‘80s and early ‘90s no doubt remember TV personality Don Herbert, or “Mr. Wizard,” the creator and star of two popular TV shows aimed at teaching kids all about the wonders of science.

It’s not hard to forget some of the fun experiments Mr. Wizard conducted on his shows, but it’s the crabby old guy’s impatient attitude with kids that we’ll remember most. Check out a supercut of Mr. Wizard basically being a jerk to the poor science-starved kids on his show. Over and over again.
