MacGyver: What You Didn’t Know About The Classic Show
John Koivula Created the “MacGuyverism”

John Koivula became a central part of MacGyver’s crew, He became the show’s scientific consultant and was called on whenever the cast and crew had questions about MacGyver’s subject matter. Writers would work together to think of logistical problems and Koivula would come up with the solutions—or what he would eventually refer to as “MacGuyverisms.” If Koivula deemed something as too danger (or thought it might cause viewers to attempt the same MacGuyverism at home) it vetoed the idea and it was back to the drawing board for the cast and crew.
