**Riddle**: Two fathers and two sons went fishing one day. They were there the whole day and only caught 3 fish. One father said, that is enough for all of us, we will have one each. How can this be possible?

The answer of this riddle is that there was the father, his son, and his son’s son.

When we hear that two fathers and two sons went fishing, we gather 2 and 2 without thinking, and assume that there are 4 of them in total.

Nevertheless, we forget that there may be another possibility. A father, his son, and his son’s son make two fathers and two sons. In other words, 3 people can be 2 fathers and 2 sons in total. As it is understood, 3 fish will be enough for these 3 people.

Answer: There was the father, his son, and his son’s son. This equals 2 fathers and 2 sons for a total of 3!
