Summary[]
Dejected because Helen has told him that women don't find him attractive, Stanley Roper goes down to The Regal Beagle where Jack is filling in as bartender for the evening. A sympathetic Jack promises Joan, a pretty girl at the pub, that he'll take her to dinner the next evening if she'll sit with Roper and feign interest in him to boost his ego.
Roper is thoroughly enjoying himself, until Chrissy and Janet arrive along with Mrs. Roper just in time to see him getting a kiss from Joan. Mrs. Roper quickly leaves, totally crushed, but when the girls tell Roper he's been found out, he's triumphant. Mrs. Roper is ready to leave Stanley until Jack reveals he set the whole thing up, and she decides the best thing for their marriage is that she let him go on thinking he's a heart-breaker, even if she knows the truth.
