10 Family Guy Characters Killed Off For Good

You might look at this father-and-son pair and think that the apple has fallen very far from the tree. As it turns out, Francis Griffin is Peter's stepfather - something that only comes to light after the man passes away.

A devout and overzealous Catholic, the Irish-born Francis is disapproving of almost everything Peter does. He's especially cruel to Lois, whom he calls a "Protestant whore" and constantly badgers to get Stewie baptised. The whole family dreads his visits, as his inability to keep his opinions to himself usually gives them a lot of unnecessary grief.

When Meg turns 17, Francis attends her birthday party at the Griffins' house, and Peter, misreading the room completely and showing up dressed as a clown, somehow ends up crushing his father to death by riding a unicycle down the stairs.

Nobody seems particularly torn up about Francis's passing; in fact, Lois and Brian even excuse themselves to cheer and jump for joy outside.
