check out -

the dogs on the riverbanks (wtf!)
the fish.
the shitty little involuntary spasm he seems to have when it goes to the icebergs on a boat shot for the first time.
the spinning boxes (ha ha)
when he comes up behind himself and the sync all goes to pot.
when the oooowoogas kick in for the 2nd time (how shit does that sound! ha ha) (and how they last an innapropriately long time)
the exagerrated upper torso movement when he is flying
the clenched fist (ha ha ha ha!)
the tribal jumping on the spot as if he needs a shit
i personally find all the motorbike scenes hilariously shit too

Above all though, its the 1 billion % committment given to it all by the Hoff, and the fact that you can see he genuinely thinks its all fucking class. ha ha ha ha.

I dont think its possible to actually sit down and think of a better hilariously shit music video/song combo.I also love the way that each 'scene' is short enough for the next one to have kicked in just as you are finished pissing yourself at the current scene.
