A name that stands out, get up some name listings online if you must, and choose the least common name, commonly whatever names seem to fit the character's personality will do fine.

Some examples of fake government names could be "The Ministry of Silly Walks" (from the comedy sketch by Monty Python), "The Department of Utter Nonsense", or "The Bureau of Imaginary Affairs". These are fictional names often used for comedic or satirical purposes.
