Found a Halloween how-to at Instructables for creating melon brains. This project brings back trick-or-treating memories. I encountered two homes during my youth that featured the old “touch the brain” gag. One was undoubtedly spaghetti encased in a brown paper bag, while the other appeared to be some sort of jello mold. I distinctly remember the spaghetti brain’s house because the doorbell was rigged to sound like a truck horn. It scared the hell out of us. The door opened to complete darkness; a moment of hesitation and then two witches leapt out carrying a bag purported to hold the brains of Igor. Good stuff!
