You hear two words and suddenly you’re doing the voice. Sitcom catchphrases have a way of escaping the show and becoming part of everyday conversation — sometimes whether everyone around you likes it or not. Does Joey’s “How you doin’?” have more swagger than Sheldon’s “Bazinga!”? Can Steve Urkel’s “Did I do that?” outlast Homer Simpson’s “D’oh!”? And how do you even judge “Yada yada yada” against “Whatchu talkin’ ’bout, Willis?” There’s only one way to settle it: vote through the head-to-head matchups and crown the greatest sitcom catchphrase ever.
