Just a product of society that's lost its good manners.
Set in Springfield, the average American town, the show focuses on the antics and everyday adventures of the Simpson family; Homer, Marge, Bart, Lisa and Maggie, as well as a virtual cast of thousands. Since the beginning, the series has been a pop culture icon, attracting hundreds of celebrities to guest star. The show has also made name for itself in its fearless satirical take on politics, media and American life in general.

Principal Skinner announces that Mrs. Krabappel was called out of town and budget cuts dictate that, until she returns, the school's two fourth grade classes will merge. Bart reluctantly shares a desk with Nikki and develops a flirtatious rapport. Bart talks to Grampa about his new crush, and at Grampa's suggestion, gives Nikki a kiss. But when Nikki starts sending Bart mixed signals, he swears off women forever. Meanwhile, Lisa's classmates ostracize her for being an overachiever, and First Lady Michelle Obama, a self-professed nerd, comes to Lisa's defence.
