Garth Marenghi is a fictional parody of bad prolific horror novelists of the 1980s. The character, created and portrayed by Matthew Holness, is the central character of Garth Marenghi's Darkplace, a comedy series on Channel 4 in Britain. The series features a show-within-a-show, with Marenghi portraying Dr. Rick Dagless, a doctor in a haunted hospital.
Marenghi has stated that he has written more books than he's read. This likely makes him Andy Schlafly's hero.
