Less than Perfect (2002)

Season 1: Episode 13

Will leaves his apartment to be taken care by Claude while he's gone, and tells her she can bring whoever she wants to it. She quickly organizes a small party just for her closest friends, which does not include Kipp, who stole her idea for a story. Lydia gets obsessed in finding a crystal gazelle she gave to Will and after she does she spends the whole evening trying to rescue it from the fish tank. Kipp drops by unannounced and discovers by accident that Will has his mom's phone number on his speed dial. Turns out his mother and Will have been sleeping together for a good time now, which causes a lot of awkwardness on both parties, and it's up to Claude to fix things.
