I watched a documentary recently that pointed out that, despite how clumsy their shape might make them look, gaboons in particular can strike in a 180 degree radius. They also claimed that their striking speed has been measured and clocked in as being faster than lightning striking the ground. If I am not mistaken they also have the longest fangs of any venomous species at around 2'' (correct me if I am wrong there). That is not a snake you want to mess. I understand the temptation, they are beautiful animals, but that seems likely to wind up taking a nice long dirt nap thanks to his efforts.
