Despite Carla's assertion to take matters into her own hands, Sam finally gives up permanently to Gary.

When City Councilman Kevin Fogarty comes to Cheers on his re-election campaign spouting a whole lot of political nothings that nonetheless woos the crowd, Frasier bets the gang that he can even get a trained monkey on the ballot and garner 10% of the vote. Without a trained monkey in sight, Frasier chooses Woody as a good surrogate. Frasier does indeed get enough signatures to get Woody on the ballot. Woody helps his own political cause when Holly Matheson, a local reporter covering the City Hall beat, mistakes Woody's farm talk as an analogy for the problems of City politics. In an early poll, Woody garners 8% popular support, enough for the gang to concede defeat to Frasier.

The day after, everyone has a hangover. What's worse, Carla, who imbibed and got drunk herself, has a sneaking suspicion that she took someone home and slept with him, that person she believes being one of the Cheers regulars. She confides in Sam alone, and after he tells her it wasn't him, she panics and they both ponder who it could have been, with her worse nightmare having it be Cliff. When her bed-mate ultimately reveals himself, Carla and Sam have to decide how best to handle the information. Two other revelations come to light in the aftermath of the drunken spree. And Sam makes an admission of his own to Carla to make her feel better about her own further revelation.

Don Sentry walks into the bar and into Rebecca's life. He's the repairman called in to fix the bar tap. Although Don is not Rebecca's usual type, Frasier talks her into taking a chance when she states that someone like a Don is what she should be going after. Quickly, she falls head over heals, but Sam thinks she's settling for second best. He wants Rebecca to be his fall-back if in a couple of years he has not found "Mrs. Malone". Rebecca shoots back that he is an aging Lothario way past his prime. Frasier suggests to Sam, who is hurt by Rebecca's comments, that perhaps there is some truth to Rebecca's assertion about him and that he would benefit by group therapy for sexual compulsives. Sam does go to the meeting, and after a rough start, he does admit that perhaps he is no longer happy with his life.

Whilst watching the National Cable Ace Awards, the gang sees ex-waitress Diane Chambers winning the award for best writing in a mini-series. This leads to Sam calling Diane to congratulate her, and to find out that she is married and has children.

Sam strongly believes Diane is lying and becomes really shocked when she walks into Cheers the following day to meet Mrs Malone. Meanwhile Rebecca's boyfriend Don proposes to her and she accidently says no, ends up heartbroken and agrees to play Sam's wife to fool Diane.

Sam and Rebecca have dinner with Diane and her husband, Reed Manchester. During the dinner Don arrives and proposes to her again, and this time she manages to say yes!
