A fan favorite, Kerfeld was known for his quirky sense of humor and bullpen antics. When asked in 1987 what he would do if he had only a week to live, Kerfeld replied, "I'd get Hulk Hogan, Brian Bosworth, Charles Barkley and I'd have a four-man tag team match with the Four Horsemen." Pondering alternative career options after a 1988 shoulder surgery, Kerfeld said, "Arena Football is first. Then the World Wrestling Federation. Maybe go back to college and get a brain surgery degree. Or become an assistant clubhouse man. Or go to Harry Wendelstedt's umpiring school."
