“Family Guy” has a ton of running gags, but there’s one so subtle that occurs in every episode that even hardcore fans might have missed it.
“It’s so simple that it’s easy to miss, but [a user] on Reddit pointed out that, in every episode of “Family Guy,” at least one character says some version of the sentence “What the hell?” Additionally, [other show fans] noticed the same thing. However, don’t feel bad if you have been watching “Family Guy” for years and never noticed this. It’s easy to miss because it is a common phrase, it is not always the same character saying it, and sometimes there are alterations to the phrase. This includes “What the hell is going on here,” “Where the hell are we going,” “Who the hell is this,” and even “To hell with parliamentary procedure.” So, in reality, instead of the phrase “What the hell” appearing in every episode, it is only the word “hell” itself that truly appears in every episode.”
