You can't make this stuff up. Here is the write up from congress.org:
In its final action of the week, the House cleared a Senate bill that would remove the pejorative “lunatic” from the United States Code. The lone House dissenter was Texas Republican Louie Gohmert, who insisted that lunatic should be retained, pointing to his fellow Members of Congress as living, breathing examples of the term. The bill awaits the president’s signature.
