==="The Genesis Tub"===
In preparation for the school science fair, Lisa performs an experiment in a [[petri dish]] to see if [[cola]] will dissolve her baby tooth. Bart gives Lisa a static electric shock, claiming it is part of his project to prove that "[[nerd]]s conduct electricity". The electric charge is then passed on to the tooth when Lisa tries to touch it, causing it to undergo an unusual reaction which creates a race of miniature beings. Lisa discovers this when inspecting the contents of the tub with a microscope, noting that their rate of evolution is accelerated. Bart destroys some of the [[ecosystem]] in Lisa's tub universe with his finger, and the tub people retaliate by sending a squadron of spaceships to attack him. The inhabitants of the tub then shrink Lisa to their size with a miniaturization ray and beam her down into the tub, where they explain that they regard her as God, and Bart as the Devil.

She says she can protect them from Bart if they return her to normal size, but they lack the necessary technology. Suddenly, Bart takes the tub to the science fair to the tub people's horror and submits the tiny universe as his own project, and now Lisa is forced to watch from within as Bart wins first prize. Now stuck in the tub for the rest of her life, Lisa starts to order around the tub people.
