Who's the stupidest person you ever met?

In real life on online?

either, just in general

Who is it and what did they do?

I knew one girl, she was English.
She asked me if Ireland was to the East or West of England.
She also told me that Morocco was in Europe, because it's close to Spain. I corrected her, and she told me I was wrong.
We were in Morocco at the time...
