The definitive origin of April Fools' Day is disputed, but the most popular theory dates back to 16th century France. In 1564, France reformed its calendar so the new year began Jan. 1. Some people refused to change with the calendar and continued to play pranks the last week of March during the old new year. Those who fell for them were called Poisson d’Avril, or April Fish, which today remains the French term for April Fools.
While the origin may be lost, the Internet has ensured its tradition is not. Businesses seem to play tricks best, as they've got the money to make it look real. Here are our three favorite April Fools' pranks from today.
Bieber or Die
Funny or Die's prank is one of those rare April Fools' jokes that you can enjoy even while knowing it's fake. Justin Bieber, the 16-year-old R&B star and teen heartthrob, announces he's bought Funny or Die. Meet Bieber or Die. Justin tells us how amazing it is to be rich, famous, and young. "I talk loudly in libraries," he says, "and I swim directly after I eat." Never mind Bieber or Die; I say viva la Bieber!

No-Underwear Subway Ride
Every day may be April Fools' Day at Improv Everywhere, but today it really outdid itself. The ante was upped on the yearly pantsless subway ride, and more than 1,000 people rode the subway sans pants and underwear. Watch the NSFW (though blurred, so safe for the mind) video below!
In-n-Out Coming to New York
When a restaurant chain has a ravenous cult following, you really can't joke about opening new outlets. Not even on April Fools' Day in New York. But these very real-looking posters caught New Yorkers off guard this morning and, briefly, made them believe. Evil!
