Doberman Pincher plays with waterslide

Here is a funny video featuring a doberman pincher going down a waterslide.  The video was posted on StupidVideos and was pretty hilarious watching.

Commentary on the video:
I have seen videos of dogs playing with pools and even swimming in them, but going down waterslides?  You don't see that everyday.  By the way, do any of your pets do anything like this?
