(I thought of this one on the D.C. beltway the other day.  No, I 
wasn't driving -- but I'm just fascinated with way one's mind wanders 
in moments of mental solitude.)

According to the chocolate frog card, Dumbledore is famous for his 
defeat of the Dark Lord Grindelwald in 1945.  Does anyone else see 
the WWII connection here?  Is it plausible that such a huge war was 
the result of upheval in the Magical World -- or even that Hitler was 
controlled by or WAS Grindelwald?
