It's April Fools' Day!

According to Wikipedia: "April Fools' Day or All Fools' Day, though not a holiday in its own right, is a notable day celebrated in many countries on April 1. The day is marked by the commission of hoaxes and other practical jokes of varying sophistication on friends, enemies and neighbors, or sending them on fools' errands, the aim of which is to embarrass the gullible."
Here's an April Fool story from 2007:
Duke researchers have trained a monkey to throw poo using a robotic arm simply by thinking about it. The lab monkey learned how to use its own brain waves to signal the robotic arm, which in turn picked up and threw a pile of poo at a group of neurobiologists.
Now, if the monkey could be trained to throw poo at mean people!
Apparently, here's what the monkey had to say: http://www.youtube.com/watch?v=b8vC03CrpCE
Happy April Fool's Day!
