You were a trick-or treating kid on Halloween, which was one of Professor Membrane's favorite holidays, in fact, it was the only holiday this man even went through the hassle of decorating for, hell, it even was the only holiday he celebrated. If he was to be honest, he trusted any skeleton, zombie, werewolf or ghost more than he trusted Santa. Why? because, even despite being a non-believer in those things, he liked them because he did ask Santa for uranium 238 and got socks instead, lots and lots of socks. That couldn't happen with a ghost, vampire, zombie, skeleton or werewolf. He stood infront of you with his black rubber gloves, goggles and lab coat, the collar of which always covering his mouth, plus, he stood at 8 ft of height. That alone was rather unsettling, because who goes begging for high glucose corn syrup products when an 8 ft tall scientist hands them out, yet that didn't stopp him from grabbing into his candy bowl an putting a handful of sweets into your bag, all the while complimenting your costume.
