Actor: Richard Dean Anderson
TV Show: MacGyver (1985-92)
The Woody Allen of TV Adventure stars preferred to use his brain to get him out of sticky situations and help take out the bad-guy trash. And if you could suspend your disbelief (that's what TV was about in those days), you were in the presence of a certified genius every week. MacGyver relies on scientific principles to break locks, start engines, and remote detonate explosives in the face of evil. But if you were trapped in a walk-in freezer with the guy, and he asked you to get him a lemon, some twine, and some steel wool, you'd probably see that mullet in a slightly different light.
