This week “Jeopardy!” Is showing it’s earliest episodes that featured Alex Trebek as host. And last night’s was his first episode ever, from 1984. And holy smokes is it Must See TV. It’s like a time capsule. The cringey clothes. Even worse glasses. Trebek’s unstoppable 80s mustache. The questions that are barely more challenging than something you would’ve found on “$10,000 Pyramid” or “Match Gamw.” I mean, the Final was “This holiday will take place on the third Monday in January” because the concept of MLK Day was still so new to them. It’s like finding a significant, historic cultural artifact. And much more interesting than “Celebrity Jeopardy” ever was.
