Caroline in the City - Season 4 Episode 8

Jealousy between Richard and Annie reaches a new height when Richard wants to attend an operatic recital to which Caroline invited Annie months ago. The two squabble so childishly that an infuriated Caroline tells them off loudly - and the insulted diva walks off the stage and refuses to return. When Caroline sneaks into the star's dressing room to apologize and beg her to finish the recital, she winds up rubbing her feet and getting drunk with her on champagne, and returns home to find that Richard and Annie's mutual anxiety about her whereabouts has produced a sort of truce. Meanwhile, Del finds himself taking a reluctant ethical stance when he is invited to an executive charter jet weekend on condition that he persuades cartoonist Reg to introduce a white character into his black-only post-apocalyptic fantasy world; and a furtive pair of nerdish animators fall madly in love with Caroline but are unable to speak in her presence.
