20 Mind-Blowing Facts You Didn’t Know About Family Guy
16. "What The Hell" Is Said In (Almost) Every Episode
In the pantheon of obscure running jokes this has to be one of the most deceptively subtle.

It's a nice little running statement, probably done as a show of its ability to casually drop more adult language than its counterparts. It is often misreported that the phrase is used in every episode, which is unfortunately not the case; at the very least Season 3's From Method To Madness the word doesn't appear at all.
