I am looking for a fantasy/science fiction movie which has galaxy cops coming to Earth. The scene that I remember is one of the characters identifying a cow as the ugliest creature in the universe.
A group of young adults, none were big name stars at the time of the movie, arrived on Earth, in America. They were looking for a criminal or a group of criminals. They landed in a small town. The character that id'd the cow as "the ugliest creature in the universe" was an ugly, short, fat character. He had a pointed head and waddled wherever he went. That is pretty much all I remember.
