"Father of the Groom" is a short story by Harry Turtledove, first published in the anthology The Mad Scientist's Guide to World Domination (Tor, 2013) edited by John Joseph Adams. It was reprinted in We Install and Other Stories (Open Road Media, 2015).
Professor Tesla Kidder's son Archie was engaged to be married. While Kate was normally a pleasant enough young woman, the pressures of preparing for the wedding got to her. One of her bridesmaids referred to her as a "Bridezilla" within Professor Kidder's hearing and got him to thinking. This wouldn't have mattered except Kidder was a mad scientist which led to an "unfortunate incident".
