Did you know that humans and chimps share a genetic mutation that helps them break down alcohol? Scientists say that the benefits of such an expanded diet may have even led evolution to favor an attraction to alcohol.

Well apparently Chimps have used this expanded diet by learning to fold or crumple leaves inside their mouths to produce a drinking tool. They dip these "leaf sponges" into their preferred drink, palm wine, and then squeeze the leafy tools in their mouths. Maybe these Chimps spent some time at a Gotham Holiday party observing humans to learn how to do this.

BTW scientists have spent 7 years studying this and found that mostly male chimps are drinking.
