Look at the figure below, which shows 15 men.
The figure is
subdivided into 3 areas (upper left, upper right, and the bottom half).

By exchanging the upper 2 parts of the figure, one gets the figure below.
This new figure however only shows 14 men!
(If you don't believe what happened here: print it,
cut it, and try it out yourself!)

The Question: Where did the missing man go?
