On Happy Days, Fonzie's "Aaay" could mean just about anything. The one-word catchphrase uttered by Henry Winkler, who played the Fonz (Arthur Fonzarelli), expressed everything from humor to seriousness. Though it's not even really a word with an official spelling -- "Eyy" or "Eeey" or Ayy" -- it's the one-syllable line that viewers associate with the character and the show, which ran from 1974 to 1984. Fonzie was a perfect TV character, and despite the stereotypical early-'60s tough-guy facade, there was a lot more to him -- especially as the show went on and he became its center.
