This is a video of a young gorilla who repeatedly knocks himself over trying to pound his chest. That must have been quite the pounding! Or he's completely uncoordinated. I hate it when I try to show off and wind up embarrassing myself. That's every time, by the way. Now I'm not saying this little guy will never be the dominant male of his gorilla tribe, but I am saying gorilla tribes need betas too to sit around and watch the alphas have sex with all the females. Try not to stare.
Keep going for the video but if you only have five seconds skip to 0:40 for the best one.
Thanks to Allyson S, who informed me all the flies in the video gave her anxiety. Ha, you should see my apartment. I think they breed in my sink.
