This Emmy- and Peabody Award-winning family comedy series opens its eighth and final season with "That's What Friends Are For," which finds Bow (Tracee Ellis Ross) yearning for more couples friends in their social circle. She manages to persuade a reluctant Dre (Anthony Anderson) to go with her to a political fundraising event, but he's convinced any husbands attending will be boring duds. They're pleasantly surprised, then, to discover Michelle Obama is the evening's special guest, and shocked when the former first lady accepts a dinner invitation at their home.
