Solve this Riddle!

Dang

Thought so

How about this:

An old man dies, leaving behind two sons in his will.  He orders that they have to compete in a horse race to win his full estate, but whoever has the slowest horse wins.  Both sons are perfectly intelligent (and both really want his estate), and they compete in the race at full speed.  Why?

You really had me stumped, but a few of my friends helped me out. The answer was that they both switched horses, so that way the winner of the race would be the one that originally had the slower horse. Here is one for you:

Okay, so there is a Grandfather, a father, and a son, which we will call A, B, C. A is the father of B. That is one father. B is the father of C. So that is two fathers. In a similar way, B is the son of A, and C is the son of B. In that way, we have two fathers and two sons. Which are 3 people.

OK correct
