Why did the chicken cross the road specifically on Aug. 15? Because it's National Tell A Joke Day, of course!
Chickens are out in full force (Why did the chicken cross the basketball court? He heard the referee calling fowls! ) and no joke is too corny (What do you call a chicken crossing the road? Poultry in motion! )
The only rule on National Tell A Joke Day is to laugh -- even a little. And tell a joke -- even a one liner.
Laughter not only releases feel-good brain chemicals, but it also gives the ab muscles a tiny workout.
Laughing is so beneficial, it's actually studied for its therapeutic effects. Gelotology looks at laughter and humor from a psychological and physiological perspective.
People have been joking around since 1900 BC, according to the National Day Calendar website .
And although the origin of National Tell A Joke Day can't be traced, it just might've started with a chicken.
Everyone knows the chicken crossed the road just to get attention. (C'mon, you laughed.)
