Will & Grace (1998) : 3x6

Grace rejects an ex-boyfriend's suggestion that she participate with him and his girlfriend in a romantic escapade but when she confides in Will and Karen -- who fall down laughing at the prospect -- the conservative Grace considers throwing caution to the wind. Meanwhile, Will tries to help a newly employed Jack meet a customer at a clothing store by prompting him with witty lines like a latter-day Cyrano de Bergerac.
