Who defeated Napoleon at Waterloo?

There happens to be a town in North Dakota called Napoleon.  The people there are either total idiots, or very clever.  Years ago when Lord Kadizzle was employed at a power plant he was giving a group of students from Napoleon a power plant tour.  As the students looked over the huge scale model of the power plant Kadizzled annouced to the students.  "I will give a prize to the person who can tell me who defeated Napoleon at Waterloo".  Immediately one student replied, "Napoleon doesn't play Waterloo".   Now this was either a very clever funny comment, or the student was a complete idiot regarding history. 

Yesterday Kadizzled was wandering an art show in Gold Canyon, AZ.   Kadizzled overheard an elderly gentleman mention he was from North Dakota.  Kadizzled engaged the man in conversation and found out he was from Napoleon.  Kadizzled told the old man about the incident with the student at the power plant.  After relating the story to the man Kadizzled thought the man got the humorous part of the story, but the man asked " What sport was it, basketball or football?". 

Now the question arises, are the people in Napoleon so ignorant they have no clue that the Duke of Wellington defeated Napoleon, or do they get this question so often they each have a clever answer?  No offense to the people of Napoleon, but my guess is they have no idea of what Waterloo was.  I hope I am wrong, and if anyone from Napoleon can clear this up, let me know.

I am already in great trouble with the people from Hoople, North Dakota.  I have become found of the term Hooplehad and use it often in a derogatory way.  The HBO series Deadwood made the term popular.  The people in Hoople are not happy about it.  Now all I need to do is piss off all the people in Napoleon.
