When I was in first grade—we’re talking 1970 here—I was excited to discover that the high school drama club was going to put on a play called The Ghoul Friend. I was already a dyed-in-the-wool horror geek by this time, and I pestered my parents until they agreed to let me go. I don’t remember much about the plot after all these years, but I remember there were lots of cool monsters . . . and at the end the actors took off their masks to reveal they were all humans in disguise.
