Everybody talks about how smart children are, but apparently they aren't all smart enough to know you should never climb into a mailbox.

Four-year old Jakob Strauss in Austria ran into the box after a mailman left it open, then inadvertently latched the door behind him. The next natural step was for him to freak out and scream for help. Unfortunately, nobody would help him because all passersby thought it was part of a Candid Camera-style prank. Thanks, reality TV.

Firefighters eventually freed the boy using bolt cutters, but not before the whole incident ensured the kid would have panic attacks every time he receives a birthday card for the rest of his life.

"He told his mum he would not be going anywhere near any postboxes any more and he never wants to see a letter again for the rest of his life after being stuck in there with so many of them," said a spokesman.

It isn't just kids, though -- all sorts of people are always getting themselves into sticky (or tight, or cramped) situations.

Like this guy, who climbed into a sewer trying to find a set of keys.

Or a woman in Kansas who somehow became stuck to a toilet seat for two years and refused to get up.

Then there were 24 of the most unfortunate people ever: left dangling upside-down in a roller coaster for four hours.

And lastly, here's a real brain-buster: A small child manages to trap himself in a crane game. How did he get in there?! It makes no sense!
