It’s so simple it’s easy to miss, but u/ballerific on Reddit pointed out that in every episode of Family Guy at least one character says a version of the phrase “What the hell?” Also, fans of the Family Guy Addicts blog noticed the same thing. However, don’t feel bad if you’ve been watching “Family Guy” for years and never realized it. It’s easy to miss because it’s a common phrase, it’s not always the same person saying it, and sometimes there are changes to the phrase. These include ‘What the hell is going on’, ‘Where the hell are we going’, ‘Who the hell is this?’ and even ‘The hell with the parliamentary process’.
So in reality, instead of the phrase “What the Hell” appearing in each episode, only the word “Hell” itself, which actually appears in each episode. Here’s a video montage of Family Guy characters saying, “What the hell?” and similar phrases in each episode, which really demonstrates the writers’ dedication a bit.
While this one-liner is simple, once viewers know about it, it allows them to spot a pattern and feel like part of an inside joke. Knowing the one-liner is coming eventually, fans who listen to it will surely hear it and experience the variety of uses for the joke. “What the hell?” is such a versatile expression and part of almost everyone’s vocabulary that the possibilities are almost endless.
