April Fools' Day, or All Fools' Day, is a traditional day for playing pranks on unsuspecting people. In many countries, including the United States, it is the custom on this day to play tricks on people. A favorite joke is to send someone on a fool's errand (a search for something that does not exist) or make crazy claims that there were three leatherback sea turtles within 6 meters of one another on a cold night in March.

In the United States, the victim is called an April Fool. Got you!
