Public service announcement: MacGyver is on Netflix Instant, and you should stop whatever you are doing right this second and go watch it. I've been sick the past few days and MacGyver has saved my life—LITERALLY. In my experience, you can't go wrong with any MacGyver episode, but here are the Netflix descriptions of a few that might be good to start with.
MacGyver is accused of having a fear of commitment by the women in his life. A dream takes him back to the Old West with its mail-order brides. ("MacGyver's Women," Nov 12, 1990)
MacGyver discovers his family name was disgraced during the Middle Ages. He is then knocked unconscious and transported to the time of King Arthur. ("Good Knight MacGyver, Part I," Nov 4, 1991)
After outwitting Sir Duncan and escaping the clutches of Morgana, MacGyver and Merlin search for the kidnapped Cecilia. ("Good Knight MacGyver, Part II," Nov 11, 1991)
Two guys whack a priest in the head with a metal pipe, drag him to a construction site, and rob him of everything valuable. MacGyver investigates. ("There But for the Grace," Feb 18, 1991)
