Gorillas are pretty darn aggressive animals and they can actually inflict a lot of harm to the ones who get unnecessarily close to them so whatever the reasons are that you feel to approach one someday make sure you are all covered up in a protective gear because you may never know when a routine gorilla turns into flesh chopping king kong.
These two gorillas were apparently minding their own business inside the enclosure when a couple of people popped up right in front of them. Now kids are pretty excited to see the animals inside the zoo and it is like their dearest wish to be close to them and even get to touch them. But we all know that this is not at all possible and sane as well because whatever happens these are wild animals. So when a kid decides to go all gorilla by beating his chest in front of what seems an Alpha male, the male could not resist the charm of the kid and came bashing right at the window to make sure he had the good out of the kid. The window actually cracked to a small extent and we can have an idea what strength these animals hold.
