Mr. Clark is the beloved 8th grade counselor at Canandaigua Middle School. He has a wife and 3(?) children. He has counseling abilities far beyond any other school counselor, and is often depicted with celestial powers of some sort.
There was a brief religion based around him, which was given the peculiar nomenclature of "Clarkism". The church of Clark was very quickly overthrown by Maharism, mainly due to the sheer power and high quality meme of grand Maharian knights, Stein and Donovan, who are rumored to still roam the counseling office long after the brutal battles.
Even though the Clarkist belief may have dwindled over the years, no one can deny the power, zest, and counseling ability of our venerated school counselor, Mr. Clark.
