Lord Griffin rocks the fanciest attire possible.
"Peter, Peter, Caviar Eater"
Season 2, Episode 1
Peter Griffin is usually a crass man with simple tastes and a simple wardrobe. So when the Griffin family inherits Lois' wealthy aunt's fortune, he completely transforms his mannerisms and dress to fit in with the refined upper crust of Rhode Island. "Lord Griffin," as he calls himself, now sports formal dinner attire befitting of a gathering at Downton Abbey, complete with gloves, walking cane, tophat, and opera glasses.
