Killer Party

Gary wants to throw the party of all parties. So he does. Trouble is, he throws it in Wyatt's house while his parents are gone. Unexpectedly, Wyatt's parents return home. Trying to fix the situation, Lisa zaps Wayne and Marcia Donnelly's brains into the brains of sixteen year old party-goers, as well as zapping Emily and Al Wallace's brains. From then on, all heck breaks loose. Wyatt's mom hits on Gary due to his great set of buns and Gary's dad shows off his stomach. Later, Chett holds everyone hostage with a gun.

M. et Mme Donnelly étant partis en week-end, Gary et Wyatt décident d'organiser une soirée. Mais les parents de Gary lui interdisent d'y aller. Lisa prend alors les choses en main et transforme Al et Emily en gamins de 15 ans.
