This Very Smart Orangutan Actually Builds Himself A Hammock!?

A 14 year old Orangutan, in a Thailand zoo is fascinating the world with this video. Watch how it very calculatingly constructs a hammock for itself. The way it ties the knots, and tests the strength, reties it, and checks it again, is very methodical and careful. This must make some people rethink their opinions of these animals after seeing how logical, and intelligent they truly are.
