There are eight flies and two barns, each barn containing some amount of horses. Four flies fly into the first barn and the remaining four flies fly into the second barn.

A third barn is then constructed and some amount of horses are put into it. Four new flies fly into that barn.

You then find that the total amount of horses in the first two barns is the same amount of horses in the third barn. What has happened?

Here's a clue:
When a fly flies into a barn there's an instantaneous connection between all the horses in the barn (their mouths, specifically) and the fly. The connection is this: for each horse, new horses are added. How many? The same number of horses that were already in the barn. Take this connection seriously. It is the key.

Actually, this clue is all you should need to understand fully what's happened. While the answer is simple, you need to think laterally to solve it. However, the full explanation is just beyond what'd fit in one post, so I'll omit it for now.
