That's because you clicked on the link above, which were the problem... if you try these ones, they should work:
While we're at it, does it appear as "0 rumbles" to you as well? I mean, when you give one, then it shows the actual amount, but if you refreshthe page, it'll be back to 0...
That's been happening to all the videos mentioned above...
And then you place the camera somewhere to record yourself playing with an animal, when another one decides to show up and stand right in front of it!! #fail
And don't forget to give it a rumble if you like it! =)
