A group of fellas in Brazi, calling themselves Os Primitivos (The Primitives), decided to screw with some would-be bike thieves in hilarious fashion: by tying an unlocked bike to a tree.

Sadly, both bike thieves appear to escape when confronted – but, at least we have great vide of them falling on their asses.
