Okay, honestly, some of the scenes in this video of out-of-context clips from Nickelodeon's 1980s reboot of Mr. Wizard hardly count as dickery. In fact, some bits just look like what happens when a good teacher tells kids they aren't quite understanding the science yet. But, then, I have a Mr. Wizard bias. And a bias toward not coddling children.
Nonetheless, there are parts of this video that are downright hilarious—"See these two pins, Stacy? Today I'm going to stick them in you!" And, of course, you must watch through to the end, where Mr. Wizard abandons a poorly dressed 1980s child by the side of the road.
