Al opposes a forced car pooling until he learns that three lingerie models are in the group. But Al realizes the models are full-figured. Al and his group are then chosen to promote a campaign by the local health board to appear in commercial advertisements to clean up over polluted Chicago. But when Al and the ladies are asked to picket outside a chemical plant where Kelly works as the Verminator spokes model, Al must decide whether or not to help close down the plant and make Kelly lose her job, or give up his fame and fortune. Meanwhile, no one seems to care after Bud announces that he has made the Dean's List at college.
