Publisher's Synopsis
Bart learns that while fat children are funny, becoming fat isn't; in 'Grrrl-Whirl', Bart's assault on girl power is undermined when he falls in love, and in 'Close Encounters of the Nerd Kind', evil space aliens Kang and Kodos get a surprise when they first kidnap Earth's greatest nerd - Bart's sister, Lisa - and get more than they bargained for!
