He lost the manual! This weekend I am watching the Greatest American Hero!
43 episodes tell the story of Ralph, played by William Katt, a goofy high school teacher handed an amazing "Super suit" by aliens. Ralph promptly loses the manual but gains the assistance of the FBI. Robert Culp's FBI Agent Maxwell frequently asks "What's the scenario?" and Connie Sellecca stole my heart.
I remember watching this with my dad.
