There are 2 fathers and 2 sons sitting around a table. How many people are there?
3 (a grandfather, who is a father, his son, who is a son and a father, and the grandfathers grandson, who is a son.)
2 (Both sons sitting at the table are themselves fathers)
actually 2... every man is someones son... therefore if there are 3 men there were actually 3 sons.

It could also be four- A father and his son, and a different father and his son [the two fathers not being related].
