If you haven't heard of the comedian called Obvious Plant, then you're about to learn a quick lesson in humor. He plants fake signs in random locations and the signs are usually hilarious. His latest venture was the LA Zoo and the results were absolutely hysterical. My favorite is probably the picture suggesting that George Washington is actually a pack of koalas stacked on top of each other. The thought of a parade of ducklings also provides a hilarious visual if you try to picture it in your head.
