Since
MacGyver was mentioned in the other thread, and it aired mostly in the 1980s, I figured we were ready to move back a decade.
I should note- I remember the 1985 Fall Preview issue of TV Guide, which included a page on MacGyver and my teenage self thought that Richard Dean Anderson was quite possibly the most beautiful man I'd ever seen. I know, me and Marge Simpson's sisters. What can I say, it was the 1980s. I also had a thing for Andrew McCarthy.
While I would not nominate
Magnum PI for one of the worst shows, I will take any excuse to link to this:
Han Solo PI
Nobody better say
Dallas, or I will cut you.
