50. The Tan Aquatic With Steve Zissou
Season: 5
Episode: 11
Original Air Date: February 18th, 2007 After Stewie Griffin is accidentally left in the sun too long, he becomes obsessed with the new skin color he has gained, and sets out to keep a fabulous tan at all times. He changes his way of life altogether, hosting "tan parties" with other people that are the same shade of bronze, and even changing the way he walks. Eventually, he would get a skin cancer scare after tanning so often, and he would decide to make an attempt to live out all of his dying wishes. The side plot featured Peter confronting a bully, only to become a bully himself, terrorizing family and friends with pranks and mean-spirited jokes before finally being convinced by Chris that bullying is wrong. It wasn't the most important of side plots, taking a major backseat to Stewie's tanning escapades, but it was enough to draw laughs as you watched Peter become a bigger d**chebag with each passing moment.
