In the final comedy sketch, Jerry asks, "Why doesn't the traffic school instructor speed more often. He's going there anyway..."

In comedy clip at end of episode, Jerry says that the amazing thing is that "for every job, no matter how objectionable, there is someone there to do it." Properly functioning markets ensure that all jobs get filled; often to do this certain jobs require an additional premium to compensate for risk or other unpleasant dimensions of the job.

Jerry does something nicer for his dry cleaner, who then extends his family a discount. Jerry's girlfriend claims to be his wife in order to get the discount.

George asks Lupe, the maid at his hotel, to untuck the sheets at the foot of his bed, because he can't sleep if the sheets are too tight, George is disappointed in Lupe, who didn't untuck his sheets as she had promised. Jerry asks George if he remembered to tip Lupe, but George forgot (no incentive after you're gone and if you're not coming back). Jerry says, "That's why communism failed."

It is scientifically proven that with incentives there is an increase in motivation to do something- this is called the Drive Theory.
