When The Simpsons become fed up with the new flight patterns at the Springfield airport which are sending loud planes over their house all the time, they take a stand and demand action from their congressman.
The politician promptly dies as he's hearing their proposal, and the family goes about helping Krusty win his now-vacant House seat and take up their cause in Washington.
Once Krusty is installed in power, he wreaks havoc on the U.S. political system - but not without getting a Springfield plane rerouting bill passed.
