That, and the fact that R^n has as many points as R (for positive
integers n).

That's not been my experience with mathematicians - they find both to
be fairly interesting.
Of course, a lot of this "weirdness" is merely due to the definition of
equality of the size of two sets. It was a convenient one to deal with
infinite sets.
