There were some puzzling moments, which I am sure sometime soon the IBM researchers will explain:
- Why did Watson come up with those strange dollar figures for the "Daily Double"
- Why did Watson come up with Toronto, when the question said "American cities?"
- And, of course, on Monday, Watson coming up with the same incorrect response that had already been given by another contestant (quickly clarified by IBM researchers that Watson didn't have the benefit of that input)
