Lol, it's brilliant isn't it! You'll never guess how i found it. I was listening to one of David Deangelo's programs (How to be a man who naturally attracts women...) and he was talking about the seven sins and seven virtues. He mentioned 'sloth'...
I was unsure what it meant so i googled it and this video came up. I couldn't believe my eyes, these creatures are fascinating, not to mention cute and incredibly funny!
