Earl is a character created by Khols, most recently used in his comic series, Summer Break.
Earl is a very boring character that works as a janitor for Dr. Khols's studio. He never shows any emotion, and all he does is clean the studio. However, before Earl became a janitor, he worked a variety of jobs, such as a doctor and as a pilot carrying tons of cash. He was still boring then, as well. As a janitor, Earl has unlimited supplies of brooms and other cleaning products. Although Earl seems to be completely boring, there might be more to him than we know.
Earl is the founder and a member of The Broom Club.
