The reason why dogs chomp at water when it's in any form other than sitting in a bowl is still unknown, but let's all agree to just put that aside today and enjoy the fact that they put on quite a show when they're attacking water coming out of a hose.
And when that show is slowed down and put to The Blue Danube (AKA the music from Kubrick's 2001: A Space Odyssey/Homer in Space), it becomes a thing of pure beauty.
