Bear cub and wolf pup playing at the Woodland Park Zoo

Now, here is something you do not see everyday: a wolf pup and a bear cub playing together.  I found this video to be pretty cute and interesting.



Interestingly, the video seems to take place inside one of the buildings at the zoo with visitors closeby.  Though the bear and wolf seem more interested in each other than their surroundings.  What do you think of this video?
