At the Memphis Zoo's cafe's gibbon enclosure, this tourist became the target of a feisty male's aggression. At the staff's suggestion, the man turned his back to the animal. The ape then let off some steam by swinging around — or at least it appeared that way.

What precipitated next is proof that our species is so undeniably boned when those damn dirty apes get the hankering to deface our national monuments.
