Responsibilities fly out the window when Eric and Annie enjoy seperate nights out on Friday. Although the reverend can't find anyone to hang out with him, so he calls a bewildered Matt. Annie is conferring with a professor (guest-star Jeff Yagher). Mary strays even further away from her parent's image of her when she is tempted to drink and smoke one night after work. Also, Mary makes friends with married co-workers Frankie and Johnny (guest-stars Chyler Leigh, Nathan West) with questionable morals while working the late shift. Matt blows Simon's chance at a big date with an older woman (guest-star Katie Stuart) when Matt is distracted by a close encounter of the female kind and forgets to pick up Simon. Also, Lucy gets a taste of the not-so-glamorous side of parenting when her and a classmate take care of an egg.

Still unemployed and bills mounting, Mary continues her downward spiral to rock bottom as Eric and Annie fight about how to effectively deal with her numerous lies and immature behavior. Meanwhile, the fear of what may happen to Mary starts to take toll on the rest of the whole family. By this, it is prompting the children to break open the twins piggy banks to help Mary pay her bills. To get the credit card company to stop calling, however, they are forced to make a risky decision. During all this, Mary CONTINUES to ignore her responsibilities.
