The Wonder Years, Season 5

Narrator:
By the time you've made it to age sixteen, you pretty much know all there is to know. About history, philosophy - the world. About life. There was virtually no situation you can't handle. Yeah, you're on top of your game - the pinnacle of poise, the essence of cool. No doubt about it - from the right thing to wear, to the right place to sit, to the right person to sit with. At sixteen, you pretty much learned it all. Well, almost all. OK. So there's one subject you're just as dumb about as you ever were. Yeah - love. Like I said, at sixteen - you've learned nothing. Nothing at all.
