Wayne Arnold: [Wayne's friend Wart has returned shell-shocked from Vietnam and is sitting on a bench in just boxers and dog tags] What's wrong, buddy?

Wart: Nothing seems to fit any more.

Wayne Arnold: [Wayne takes his shirt off and offers it to his friend] Here you go. Wear mine.

I can quote the whole series

(First lines of the series.)
Adult Kevin: (narrating)"1968; I was 12 years old. A lot happened that year."

Adult Kevin: (narrating)"In fact, he took over the factory two years later, after Dad passed away."

A.K.: "Growing up happens in a heartbeat. One day you're in diapers, the next day you're gone. But the memories stay with you for the long haul."

(Last lines of the series.)
A.K. (still narrating)"I remember a place, a town, a house. Like a lot of houses... On a street like a lot of other streets. And the thing is, after all these years, I still look back. With wonder."

Wayne Arnold:
[walking in with a fire hat and vacum cleaner] HAMSTER PATROL!

Kevin Arnold:
Get outta here Wayne!

Wayne Arnold:
Mom told you to clean up after those little rodents!

Adult Kevin: (narrating)"Adolescence. It's never a pretty sight."

A.K. (narrating)"This much was clear: My family wasn't getting along... Even for us."

Anything offensive from Wayne is considered offensive from the first 4 seasons of the show

Kevin Arnold - The Narrator: Things never turn out exactly the way you planned. I know they didn't with me. Still, like my father used to say, 'Traffic's traffic, you go where life takes you' and growing up happens in a heartbeat. One day you're in diapers, the next you're gone, but the memories of childhood stay with you for the long haul. I remember a time a place, a particular fourth of July, the things that happened in that decade of war and change. I remember a house like a lot of houses, a yard like a lot of yards, on a street like a lot of other streets. I remember how hard it was growing up among people and places I loved. Most of all, I remember how hard it was to leave. And the thing is, after all these years I still look back in wonder.
