Oh M. Gee is an extremely rich and immensely famous and very unpopular Fakegee. He was the one who founded the largest bank in The Beegee Universe. The reason for his fame and wealth is obvious, but he was very unpopular because he has a bad habit of saying his own name a whole lot. The 'Gee Dollar was named after him.
But when he died, it came as such a huge surprise that everyone started saying his name whenever something surprising happened.
His middle name is literally "Money".
