The 2014 Allentown Comic Con played host to a very special guest: Family Guy's Peter Griffin (ie cosplayer Real Life Peter Griffin), in the flesh. This goes well beyond just "cosplay".
Just look at him. He's even got the chin! But what's making this so great is that alongside the visuals it's also one of the better Peter Griffin impersonations you'll see as well.
