Cybill joins Ira at an open-mike night for his debut as a stand-up comic, which gets off to a rocky start when he faints from stage fright.

Meanwhile, Maryann displays unusual behavior, but if she seems preoccupied (to the point of wearing the same outfit two days running), it's because she thinks she may be pregnant.
