“Aaaaay!” (Fonzie, Happy Days)

Fonzie barely needed a word. A leather jacket, a couple of thumbs and one perfectly delivered “Aaaaay!” could handle the rest. Arthur Fonzarelli’s signature exclamation is a different kind of contender in this bracket: there’s no elaborate joke or setup, just pure character swagger packed into a sound. That makes Fonzie a fascinating matchup against Joey’s “How you doin’?” — two generations of sitcom confidence going head-to-head — or Urkel’s “Did I do that?”, where cool meets chaos. Does “Aaaaay!” have enough staying power to knock out the newer catchphrases? That’s for the head-to-head votes to settle.
