Lord High Everything Else

One who controls or is responsible for a wide variety of things. A reference to the character Pooh-Bah in Gilbert and Sullivan's The Mikado, who went by the title Lord High Everything Else because he was responsible for everything except executions. After the manager left, I took over her responsibilities as well and essentially became Lord High Everything else.

Someone who does a multitude of jobs. Ko-Ko, a character in Gilbert and Sullivan's comic opera The Mikado, held the position of Lord High Executioner. The only other town official was Pooh-Bah, who went by the title Lord High Everything Else. Accordingly, if you're saddled with many jobs at your place of business, with or without accompanying titles, you may call yourself or be called “Lord High Everything Else.” But no matter what you are called, your boss is still the grand Pooh-Bah.
