Who has the fish is an Einstein riddle that only 2 percent of people can solve. The claim that it is a riddle by Albert Einstein is a bit far-fetched, since some of the cigarette brands mentioned in the riddle did not exist when he was growing up (he is said to have written it as a child). Anyway, the logic puzzle, which is not his name, is therefore no less difficult, and you only need to think logically to solve it, since it does not contain any tricks. Now see if you can figure out who has a fish and if you belong to an elite group of people or not.
