OK,
Here's another one for all to ponder.
In order to travel from point A to point B, one must first travel 1/2
the distance.  In order to travel half way, you must first travel 1/4 of
the way, etc., etc., etc. In mathematical terms, the denominator
approaches infinity and we know that you can't travel an infinite
distance in a finite amount of time, therefore all motion is impossible.
