“D’oh!” (Homer, The Simpsons)

The mistake happens. The realization hits. Then comes “D’oh!” Homer Simpson doesn’t need a setup, a speech or even a complete sentence. That tiny explosion of frustration is basically the sound of knowing you just screwed up. Its biggest weapon in this league is versatility: you can actually use it, and generations of viewers know exactly what it means. That makes for a brutal matchup against something as character-specific as Joey’s “How you doin’?” Is the greater catchphrase the one perfectly tied to its character, or the one everybody steals? Homer fans know their answer. Now “D’oh!” has to survive the head-to-heads.
