The Simpson family are sitting are waiting in a taxi stuck in a traffic jam. Homer becomes impatient and indicates for them to get out, and they start running along the street. Homer gets occupied by Raphael doing a magic trick with three cards. Homer bets about $50 on the middle card, but gets it wrong and shouts 'D'oh!' He pays Raphael and Marge grabs him. They keep on running until they get to a security guard, who won't let them in. Homer headbutts him hard knocking him out, and they continue in. Outside the stage doors, a woman won't let them in, so, as before, Homer headbutts her, and the family get to the stage. Inside, David Letterman asks what they're doing here. The family runs in and sits down, as he wondered before. David doesn't think they're worth flying here. He then instructs 'Paul' for the band to play (and plays the Theme Song).
In a parody of The Social Network, when Lisa and her family went to a new shopping mall, she met some of her friends, but they said that she was lame and very dorky. After realizing she has no friends, Lisa creates a social network site, Springface to gain their attention. However, the residents of Springfield soon become addicted to it, and later have car accidents and many injuries. Will Lisa escape this situation? Will she still have friends?
The episode begins with Lisa in court, being interrogated for making a website so addictive, that it caused accidents.

While Homer and Maggie enjoy the trolley, the family sees Lenny, who is now living at the mall. Bart greases himself up and gives Otto a ride. Meanwhile, Homer eats pastries. Lisa sees some schoolmates, but when she is shunned by them, she realizes she has no friends. Homer buys a Mapple computer, and the family return home. After Homer downloads the complete works of Shakespeare, he immediately deletes it. Lisa finds out she can use the computer to interact with possible companions, so she has the idea a social network named Springface. While coding the site with the nerds, Lisa encounters Nelson, who says his favorite computer game is Angry Nerds, and proceeds to attack the nerds. When the computer work is done, the site becomes a success, not just for kids but for adults too. When Bart finds this out, he deletes Principal Skinner from his profile. Lisa is glad she has created an internet success, and Homer is glad that he has created a daughter that has created an internet success. However, Grandpa is not proud that he created an alcoholic son. Back in the court, the judge asks if the site was a failiure like Ask Jeeves, which makes Jeeves sad. Lisa says it was actually very successful, and useful, as Homer can send messages to Marge from the bar, among other things. However, it becomes too much of a success when a blogging citizen accidentally kills Moleman. This starts a riot, so Lisa decides to shut down the website. From this, she gains real-life friends.
