Birds of a Feather Boa is the seventh episode of the eighth season and 169th overall.
When Jack decides on a whim to move, Will is excited at the thought of helping him look for a place. After becoming involved in a cause to save two gay penguins from being separated at the zoo, Will starts to think closely about his dear friendship with Jack and what it would mean if he no longer lived next door. Meanwhile, during an afternoon of shopping, Karen and Grace bump into pretentious socialite Beverley Leslie, who invites the two ladies to attend his recently deceased wife's memorial "celebration." When Grace decides to try on one of the dead wife's rare dresses before the ceremony, she experiences a "wardrobe malfunction," which she must try to conceal.
