In this episode, Liz Lemon (played by Tina Fey) goes on a date with a young, twenty-year-old coffee delivery man named Jamie (Val Emmich). The date gets awkward due to the seventeen-year age difference between Liz and Jamie. This feeling escalates when Liz meets Jamie's mother (Laura Berrios). Jenna Maroney (Jane Krakowski) gets a younger boyfriend of her own. Frank Rossitano (Judah Friedlander) develops a crush on Jamie. Meanwhile, Jack Donaghy (Alec Baldwin) helps Tracy Jordan (Tracy Morgan) to coach a Little League Baseball team.

Liz develops a crush on Jamie, the new twenty-year-old coffee delivery man, and after some initial hesitation, she agrees to go on a date with him. Before the date, Liz gets cold feet, but she is encouraged to attend by Jenna, who declares Liz a cougar, a term describing "hot older ladies pouncing on their young prey". Liz agrees and goes on a successful date with Jamie; the pair agree to go on a second date. Prior to this second date, Liz goes to Jamie's apartment only to discover that Jamie still lives with his mother, who looks exactly like Liz.

Frank begins to question his sexuality when he realizes that he has a crush on Jamie. He even tries to, unsuccessfully, rival Liz to go on a date with Jamie. Later, Frank realizes that the only man he is attracted to is Jamie and decides that he is in fact not gay.

In order to become a cougar herself, Jenna starts to date Aidan, a teenage freshmen at New York University. Jenna breaks up with Aidan when he starts to annoy her by wearing heelies and playing portable video games and acting like Jenna is his mother.

Tracy is ordered to do community service in the form of coaching the Knuckle Beach Little League Baseball Team. Knuckle Beach happens to be "the worst neighborhood in New York". Hoping to inspire the team, Jack agrees to help Tracy and he donates uniforms to the team on behalf of the Sheinhardt Wig Company which is NBC's fictitious parent company. Jack replaces Tracy with Kenneth Parcell (Jack McBrayer) because he realizes that even with the newfound inspiration from both Jack and Tracy, the team is still failing. The team begins to revolt when they find out that Tracy has been fired. To counter this, Jack forms a coalition with Tracy and they replace members of the team with Grizz and Dot Com (Grizz Chapman and Kevin Brown).

Bob Sassone of TV Squad felt that the best storyline was the one featuring Tracy and Jack because of the "Bush/Iraq metaphors and the sight of Alec Baldwin dressed as General MacArthur, standing beneath a 'Fun Accomplished' sign." Robert Canning of IGN thought that the best storyline of the episode was centered on Liz and Jamie, and rated the episode 8 out of 10. Matt Webb Mitovich of TV Guide wrote that this episode "had so many fun lines", and found himself "giggling, chuckling and LOLing like a fool". He liked "the 'cougars' storyline", saying it "was a lot of fun, because Liz is best when Liz is feeling awkward." Jeff Labrecque of Entertainment Weekly wrote that "Jenna's Amber Alert affair with the soda-drinking, Heelys-gliding teenager" was "priceless". He also compared the interplay between Frank and Jamie to the relationship between Michael Scott (Steve Carell) and Ryan Howard (B. J. Novak) of The Office.
