I thought that this video was kinda cute,this video shows a bird continually sliding down the roof on a top, and it also shows that animals enjoy having a good time too. I have always suspected that when I was driving on the highway that the birds where playing as we did as children with a game called "Follow The Leader" where the leader attempted to do something so risky that no one would try and those that did might not be able to complete it, in which case they where "Skunked" and out of the competition.The birds, it seemed, were intentionally flying low right in front of the car as if to exhibit their precision flying and evasive skills.
