April Fools

Google 'best april fool's day hoaxes'. Some are pretty dang funny. Here is a favorite,

1915: On April 1, 1915, in the midst of World War I, a French aviator flew over a German camp and dropped what appeared to be a huge bomb. The German soldiers immediately scattered in all directions, but no explosion followed. After some time, the soldiers crept back and gingerly approached the bomb. They discovered it was actually a large football with a note tied to it that read, "April Fool!"

Here's another good one,

1980: Soldier magazine revealed that the fur on the bearskin helmets worn by the Irish guards while on duty at Buckingham Palace keeps growing and needs to be regularly trimmed:

The most hair-raising fact about the bearskins has been discovered by scientists recently. The skins retain an original hormone, which lives on after the animal has been skinned. Scientists call it otiose and it is hoped it can be put to use in medical research — especially into baldness.
The article quoted Maj. Ursa who noted, "Bears hibernate in the winter and the amazing thing is that in the spring the skins really start to sprout." An accompanying photo showed Guardsmen sitting in an army barbershop having their helmets trimmed. The story was picked up by the London Daily Express and run as a straight story.

And one more for good measure,

On April Fools Day in 1957 "Panorama", a news show on BBC aired footage of Swiss "Spaghetti Farmers" picking spaghetti from trees. The fake footage was aired as a joke, but viewers called in to find out how they could grow their own spaghetti trees. Instead of coming clean, the BBC cheekily replied, "place a sprig of spaghetti in a tin of tomato sauce and hope for the best."
