How can you not be happy after seeing an OK Go music video?

A few of my favorites include:
This Too Shall Pass (Rube Goldberg Machine Version)
This Too Shall Pass (The Marching Band Version)
Here It Goes Again (The Treadmill Video)

Here's their latest video for 'White Knuckles'. With the help of some very well trained, four-legged performers, this is probably one of the most difficult videos OK Go has filmed, I would imagine.
