This guy performed at my school to "cheer us up" about the Challenger disaster (I was kindergarten at the time, and the build up to the teacher onboard teaching things was enormous). I don't specifically recall the results.
I saw him no less than 3 times in person, all of them chance run-ins without prior knowledge of his coming appearance. He fucking performs everywhere, all the time, and practically for free.
I don't remember ever seeing this in my childhood, but I must have at least once, because those things look EXACTLY like the monsters from one of my worst childhood nightmares.
