Mr. Spritz Goes to Washington

The title is a reference to the film "Mr Smith Goes To Washington".

After Kent Brockman announces that Krusty has won the election, Krusty states that he is a senator. Lisa corrects him by stating that he is actually a "congressman". However Lisa's statement is misleading. Congress is both houses of the US federal legislature. Members of the Senate are called "senators" and members of the House of Representatives, to which Krusty has just been elected, are called "representatives". Both senators and representatives are members of congress and therefore congressmen/women. However, US representatives are often referred to as "Congress(wo)man." i.e. Congressman Andre Carson, Congresswoman Susan Brooks.
