I would wager that the sound of the machinery in the background might be painful to the gorilla's sensitive ears.

Always frustrates me when I see a video of a dog freaking out when it is exposed to sounds that are most likely painful to their sensitive hearing, and some derpy person is sitting there wondering what the hell their dog is freaking out about...

They have a silverback at Berlin Zoo that does this all the time. He sits perfectly still right by the window until he draws a big enough crowd of kids and parents, then BAM! he hits his fists against the window and scares the shit out of everyone. Short clip (poor quality) of it here. I am sure it is pure frustration and not fun for him though.

Poor creatures.

That being said, here is one of him hurling grass at the workers.

I can't call it, but isn't it a *dupeof=http://videosift.com/video/One-ticked-off-Gorilla-at-the-Dallas-Zoo ?

FAKE! That's QM in a gorilla costume made to look small through tilt shift.

I can tell by the voice.

So... he wants to degrade a brand by giving it to homeless, who are (sadly) perceived as the lowest of the human kind? Like... cool kids don't want to wear AF because homeless people wear it. Am i the only one who feels a dissonance between the purpose and the method? If you don't like AF just don't buy it. If you really want to go gorilla, buy a can of red paint and fucking smear it all over the AF shop...

now this looks fun, could bet on these

i'd stop going to dog fights for gorilla fighting

Gotta stand your ground. I know that's true of geese, and I hear it's true of gorillas. It's probably easier to actually pull off with geese though. God I hate those things.

Anyways, this got me thinking: Since when it's that time of year, geese land just wherever the hell they want, are they ever eaten by big cats at zoos?

Chimps and Gorillas can learn sign language. I haven't heard of it spreading in the wild though.

Filming Gorilla's what? Their habitat? Their faces? Their feet?

Now do it with gorilla masks.
