Hank receives an unwelcome surprise in the form of Carrie, ex-girlfriend and arsonist that he's forced to invite along when Karen and Becca show up to invite him to a dinner party. Stu, Marcy and Bates' talk of sexual proclivities leaves the Moodys searching for the nearest exit, but the party gets even more out of control when Carrie has a realization about Hank. Meanwhile, Charlie goes on a blind date with Mary, a "nice girl" who's more than a little inexperienced.
