I'd say Jack White is up there too. Although with him it was more stubbornness. Mistaking which side is which of the LM is one thing. Persisting after being shown multiple ways how you are wrong is something else.
White had a particularly odious brand of ignorance in that he was almost completely inept at spatial reasoning. That's an important skill to have if one wants to be a photographic interpreter.
