Because Mona refuses to delay her date when both Tony and Angela attend a PTA meeting, only Sam remains available as novice babysitter for Jonathan. He is model-behaved as always, but while they toy around Mona's diamond earrings one lands in the drain. So when Sam's coolest classmate, 'womanizer' Chad McCann, calls by, his offer to help with the plumbing emergency provides the perfect excuse to ignore Tony's formal order to receive nobody. Alas, after finding the diamond, Chad gets stuck, and more classmate follow. Meanwhile, Chad's dad bragged to Tony about his boy being a chick-magnet.
