Herbert is one of the most unforgettable characters in Family Guy, which tells the story of the quirky Griffin family. In contrast to some of the most popular characters in the series, including the famous dog Brian Griffin who is one of the best animals in an animated sitcom, Herbert is no doubt controversial and a little offensive for some viewers. Voiced by Mike Henry, Herbert is an elderly man who has a crush on Chris Griffin. But as fans know, Family Guy pushes boundaries with its jokes and storylines.
