Posted by Danny DoverYesterday, I was arguing with my friend about the existence of one sight or sound that is universally funny. He argued that since different cultures find humor in different things, there couldn't possibly be one example of something that is funny to everyone. Unconvinced, I started searching for the holy grail of funny. Immediately, I went on YouTube and starting browsing my favorite videos. Eventually, I came to the famous video of a monkey picking his butt, smelling it, and falling out of a tree. No matter how many times I watch the video I still find it funny. There is something instinctively funny about seeing how dumb a monkey is compared to the brilliance of  humans.
