So you’re sitting in your house watching television when a giant chunk of ice blasts through your roof and scares the bejezus out of you.  Your tendency is to think, "Man, what a bizarre and unlikely event" but you’d be amazed to find out that things falling from the sky happens more often than you’d think.  Simply visit this page on Boing Boing to find links to three such events and do a Google search on "frozen poop falling from airplanes" and "space junk falling to earth" to find enough stories of crap falling from the sky to make you want to invest in a Kevlar umbrella.

As the man known as "Turd Blossom" I think the odds of me being taken out by a ball of frozen poop falling from the sky are actually pretty good.
