Carol decides that they need to get rid of all of Frank's old junk. They have a yard sale where Frank tries to sell things for $15-$50, but a guy smoking a cigar will only offer a quarter in return. At the end of the day, they have only made a nickel when the guy with a cigar comes back and offers a quarter for everything left. Carol quickly accepts his CHECK. Dana is going to a college party. After a great deal of coaxing, Karen and Al convince Dana to take them with her. Karen surveys the room and picks a guy, Jeremy. Jeremy, however, chooses Al. Despite being asked to dance by 12 other guys and receiving a marriage proposal, Karen considers the whole party a waste. She and Dana then find out that Jeremy's intentions were less than pure. They rush to Al's rescue and help her get revenge.
