Meanwhile, Gloria, Claire, Mitchell and Cam all volunteer at the dance while Jay's thinly veiled guise to get out of it by pretending to want to spend time with Phil backfires. During the dance, Claire and Gloria attempt to set up Marjorie ("Saturday Night Live"'s Vanessa Bayer), an overbearing mom, with the school's principal.
