The Underachievers.

Danny Warren is a former minor-league shortstop that becomes a narc to uncover drug dealing in this situation comedy. Investigating at a high-school adult-education class, he falls for the tempting teacher. He joins a colorful group of characters that includes ex-cons, illegal aliens, and brain-dead baby boomers that cause more trouble than their younger counterparts. Swimming classes and wine tastings serve as background for a series of comic catastrophes.
