For an undisclosed amount of time, Martin Heiss was the chairman of the Council of Logic and Data and a well known debunker of all things supernatural. He was also considered a highly regarded scientific authority with impeccable credentials. During the Council's annual nondenominational winter holiday office party in 2014, Heiss received a copy of Ghosts from Our Past: Both Literally and Figuratively: The Study of the Paranormal as a white elephant gift. He read the synopsis out loud and everyone laughed. Later that night, back at his home in the Upper West Side, Heiss flipped through the book with a bottle of eggnog. He concluded Erin Gilbert and Abby Yates were completely unqualified to write it and the book was either nonsense or an elaborate in-joke. He attempted to sell his copy but every used bookstore already had numerous copies, several signed by Abby. Heiss even found a copy made out to Abby's mother.
When a video of the Electrocuted Ghost surfaced on the Internet, NY1 News brought Heiss in to comment on its authenticity. He recorded a one-on-one with Pat Kiernan, an anchor. Kiernan brought up Heiss' accolades first. Heiss thanked him. Kiernan addressed the implication of if something of true scientific interest was in the video, Heiss' words would go a long way to legitimize the Ghostbusters and everything they stood for. Heiss confirmed that would be a game changer. Kiernan asked him if the video was real. Heiss emphatically replied it wasn't and laughed. Heiss observed the public reaction to the debut of the Ghostbusters and the existence of ghosts as a form of group delusion, mass hysteria. He took it upon himself to expose them as frauds. Shortly after the Ghostbusters returned from Stonebrook, Heiss came to Ghostbusters headquarters, and demanded proof that there was in fact a ghost in their possession. Kevin informed them the Ghostbusters was a "Smartin Christ" to see them. Erin was confused and realized he meant Martin Heiss. Abby was not happy. Kevin pointed to Heiss, who was standing in the doorway. Abby directed him to tell Heiss they weren't there. Erin was confused why she said that. Abby stated she didn't want to talk to him. Kevin told Heiss they weren't present. Heiss entered the lab area. Erin greeted him. Heiss asked if it was a good time or if was the dinner rush. Abby told him to make an appointment. Erin countered it was a perfect time since they were doing some experiments.
Heiss sat down on a chair. He wanted start light and easy then asked them why they were pretending to catch ghosts. Before Erin could answer, Abby picked out how easy it was to just be a naysayer and not do anything. She contended humankind only comprehended about four percent of the universe and repeated the fact. Erin stopped Abby and reiterated they were adherents of the scientific method and she, in particular, dedicated her life to it. She picked up the Trap and told him they captured a Class 3 vapor at 4:32 pm. Heiss pointed his cane at the Trap and wanted to clarify the ghost was indeed inside the "thermos." He poked it but Abby pushed the cane away, telling him not to touch it. Holtzmann remarked, "Booyah. Emphasis on the "boo"." Heiss remarked he would really love to see it. Abby was firmly against releasing the ghost and stated they were still assessing what type of containment method to use in the lab. Abby tried to take the Trap, Erin resisted, but Abby yanked it away. Heiss was amused at his timing, they caught a ghost but he couldn't see it. Erin admitted it sounded like they were making it up, it sounded crazy, and they probably don't really look like legitimate scientists. Heiss contended they only lacked the proper equipment, like a garbage truck to hang on to the back of. Erin's smile turned to a frown and glare. Abby pointed out that came out of a man with a walking stick and floppy hat. Heiss revealed it was his mother's. Kevin leaned back from his desk and complemented the hat.
Patty cleared her throat and thanked him for stopping by. Heiss was disappointed the graciousness ran out. Erin was still intent on showing him the ghost. She grabbed the Trap and set it down on the floor. Abby told her not to do it. Erin released the pedal. Abby pulled her back and questioned her. Erin insisted it was because he didn't believe them. Holtzmann and Patty quickly strapped on their Proton Packs. Heiss got out his camcorder and recorded. Abby tried to talk Erin out of it, citing they finally succeeded at doing the thing they talked about since they were little kids and it wasn't worth it trying to impress him. Heiss thought they were something. Erin apologized to Abby. Abby told her it was okay. As soon as Abby turned away, Erin stomped the pedal and the Trap opened. Heiss cheered her on. Erin and Abby cringed. Erin quickly apologized. Heiss mockingly referred to Mayhem as Casper. Suddenly, Mayhem manifested, flied out of the Trap, carried Heiss through the window and Zhu's sign, and dropped him onto the street below. Kevin remarked he went out the wrong door. Holtzmann, Patty, Abby, and Erin ran to the window and looked. Holtzmann broke the tension and remarked he wasn't really Ghostbusters material. The police ruled it a freak accident but continued investigating. Sergeant Lance Larson was skeptical based on his injuries. Heiss was hospitalized. Two days later, the incident was mentioned in a late edition of the New York Post. Heiss paid thousands of dollars in out-of-pocket medical expenses and spent many months in physical rehabilitation. He changed his opinion on the Ghostbusters and was also removed from his position as chairman of the Council of Logic and Data. Heiss later wrote the new foreword for the revised edition of Ghosts From Our Past. He shared anecdotes about the first time he saw the book and his encounter with the Ghostbusters. He ended with a warning that life was too short to be skeptical about ghosts and this book had to be read.

He just had us do the scene several times with the core of the lines that they'd written, but we’d bounce back in and out of what Bill could come up with on the spot.
