Poetic Justice

Karen has a professor (actually a teaching assistant) try to date her by influencing her with grades. Karen tells Dana about her predicament. Dana has the perfect plan to catch Jason in his own deceitful web. While a battery that does not keep going and going causes a hitch, the plan does end up working. Mark's date comes in all her glory for a date with Mark. Actually, she is repulsive to Frank and Carol, a source of comedy to Rich and JT, and a shocking match for Mark to everybody. Mark stays out past curfew, is grounded, and runs off in Frank's truck with this girl.
