After Principal Skinner makes a chauvinistic remark towards a former female student, an uproar ensues, prompting for his demotion. Subsequently, Melanie Upfoot (Frances McDormand) is appointed the new principal of Springfield Elementary, whom divides the school into two, one for boys, and the other for girls. Frustrated with how the boys in her school are being educated more so than the girls, Lisa disguises herself as a boy to expand her knowledge, and as a result, wins the Student Achievement Award.

Did You Know?


Liquid Paper was invented by Bette Nesmith Graham (woman), Paper by Tsai Lun (man), Windshield Wipers by Mary Anderson (woman), the car by Nicolas-Joseph Cugnot or Ferdinand Verbiest (both men), Nylon Stockings by Allen Gant Senior (man - Marge is wrong), Rocket Ships by Lieutenant General Henry Shrapnel (man), Suspension Bridges by James Finlay (man), Snow Shoes by Sondre Norheim (man), Pinball Machines by Henry Joseph (man), and no one person invented Constitutional Government or the Renaissance, however women didn't have any power back then, so it's unlikely that any women had a hand in either of them.

From the front, the school is divided into the girl's pink half on the right, and the boy's blue half on the left. Yet in a scene that shows the exterior of the school followed by an interior shot, the girl's school, apparently, continues off to the left. Geographically, this should be part of the boy's school.

The Circle of Nife
20 September 2007 | by (United States florida) – See all my reviews

This is a Hilarius episode. Thats funny when Marge Simpson and Homer Simpson where young. That was cute when Lisa had a frog in her lap. Bart Simpson, Marge Simpson, Homer Simpson, and Lisa Simpson went to a performance of The Circle of Nife where $$$$$$$ staring Nathan Lane, and Matheiw Brodrieck and A Man that Named Moe. Just then the princble Skinner was on stage after the show of the Circle of Nife. Just then there where boys only so Marge Simpson gives Lisa Simpson a costume to disguise as a boy. The kids where calling her Toilet Head. This episode is Hilarius you will like the performance on the episode and the seasons.
