Chimp succeeds at making humans look like the dumber species

Not surprisingly, a chimp has managed to make a group of humans look a bit dim. According to the description of this video, the chimp  is supposedly giving the humans instructions on how to remove the bolts from its enclosure and let it out. It was a generous interpretation on the writer's part. As some astute viewers have noticed, there's a cracker on the ground in front of the glass, and the chimp's gestures aren't so much "turn that bolt there" as much as they're sign language for, "Pick up that cracker and give it to me that I may stuff it in my mouth." Humans really do see what they want to see.
