Airwolf: I believed there really was a guy with a dog that looked up women's skirts flying a top-secret combat copter at mach-1 to protect us from the badguys.
The Dukes of Hazzard: I believed that an orange '69 Dodge Charger with a Rebel flag and "01" on the doors could fly and that cop cars were built to fall apart easily. I also believed that a scroungy mechanic could fix anything.
The A-Team: I believed that a little insanity could actually bend the rules of reality and make imaginary friend real (hey, it worked for Murdock!).
Knight Rider: That computers could fit inside cars and make them drive themselves, that black cars can fly, and that black paint can make anything bulletproof.
You Can't Do That On Television: I believed that it wasn't uncommon for parents to put their kids back in diapers (this was a fear exploited by my parents to ensure that I behaved, so's I wouldn't be made to wear diapers again).
