Monkeys

I was watching one of those animal planet shows one time and heard a story about a type of primate that has a tendency to store nuts and berries in those little knot holes you find in trees. When they go back to get their treat they reach in the opening and scoop up a handful. The funny thing was sometimes when they tried to pull their hand back out they got stuck. The flat open hand could fit, but the full fist was the wrong shape and size to slide back out.
The camera crews reported they had found monkeys that had their hands "trapped" in these trees for hours, even days. They were so set on holding on to those nuts and berries they were holding themselves hostage.

Kinda makes you think.

That is all.
