LOL but concave “roads” really does make it seem like they were either “bobsledding” those bad boys down the tracks, or putting them on slippy mats in a canal, as if they were sliding on water park chutes.
Now *that* would be a funny video, if someone took mock (foam) Easter Island dudes to a water park and sent them through the “rides”. Set to the music of the chipmunks “Witch Doctor”...
Heh, heh...if The Chipmunks were to do a music video, they should have you direct it!
