Bummer. I remember my mom telling me that I was going to see something called "Pee Wee's Big Adventure" with her friend's obnoxious kid (so that she and her friend could hang out). It sounded so childish, immature to my 10-year-old self so I immediately contested it, no idea who this Pee Wee was and didn't care to know. Of course within 5 minutes of being plopped into the theater and seeing what the film was about, I knew it was going to be a great time..
I don't think I had any idea about the Playhouse either, that show just suddenly appeared one magical Saturday morning. The guy was a complete freak and it was absolutely incredible, like many I was stunned when he had his notorious fall from grace and it was sad to see that he'd never get back to the same place he was before (he did still manage to have a decently successful career in those pre-cancel times).
RIP Pee Wee Herman we will miss you!
