Beginner's Luck
by Norman Barasch, Carroll Moore

Paul after eight years of marriage decides he wants a night out.

He's supposed to be going bowling, but it's another sport - an affair with a girl from his office.

He arrives at her apartment and everything goes wrong, ending with the building catching on fire - bringing firemen and photographers.

His picture appears in the paper and that's the end of his affair and his marriage.

A year later he and his ex wife, Sally, accidentally meet and in a mishap, he injures his knee.

She sympathetically attends to it at her place and after a few drinks, they end up spending the night.

He thinks he's back in her good graces but learns to his chagrin that she now has many suitors, and one wants to marry her at once.

Paul's efforts to balk the marriage and win Sally back provide uproarious laughter
