Innovative and groundbreaking puppeteer work dominated Jim Henson's entire life, so much so that you'd think it was the culmination of a lifelong dream or something. In reality, it was more of a means to an end, with a whipped cream sundae topping of "Screw you, dad."
At 17, Henson wasn't sure what he wanted to do with his life, but like every 17-year-old alive in the past 70 years or so, he wanted to get on television somehow. It just so happened that the local television station WTOP was looking for puppeteers, so Henson and his buddy quickly whipped up a few puppets and a routine for an audition. They were hired, but the show, while popular and well received, was canceled after a few episodes.
Swooping in like a villain in an '80s movie, Henson's father then sent him to college to discourage him from his frivolous television pursuits and take a more serious role in academics or engineering. Presumably while donning a pair of cool sunglasses, Henson instead devoted his time in college even more toward artistic pursuits, doing puppetry at a nearby television station and building the chops that made him a household name a decade or so later.
