Patrick Stewart has a long and storied history with Family Guy, with the actor returning time and again to play roles old and new. As one of Seth MacFarlane's most frequent collaborators, Stewart has lent his signature British accent to 10 Family Guy characters over the years. Perhaps unsurprisingly, all of Patrick Stewart's personas have the same voice, which is where much of the comedy comes from. However, his delivery in each of his episodes also displays the actor's impeccable comedic timing and sense of humor.
