"Monkey Masterbation Spotting" has become a hobby in the South American State of illinois. A well known competitor in the sport of of Monkey Masterbation Spotting is Fred Phelps, a very vocal and fanatically religeous biggot.

The monkey wrapped his primate hand around his primate pink penis, and masterbated furiously untill he fell out of his tree. Fred Phelps watched in glee as he photographed the event so he could show the pictures to his family.
