And the 90's Horse Party (S01E05)

When Caroline learns that Max has been dodging bill collectors for years, she devises a plan to get her friend's finances back on track. Inspired by an 80's themed hipster party they discover in a laundromat, the girls throw a '90's horse party' in the diner with a stiff cover charge. The plan causes Caroline to come face-to-face with a 'Bill' of her own – her ex-boyfriend William who left her when her father went to jail. (CBS TV Network)
