Better Know A Video

This is by far the best video ever.
The Hoff stars in this amazing piece of art.
He must have been on all kinds of stuff.
I wonder how the director explained all this.
"Now look David, you are riding a motorcycle and then....
wait for it... You fly in the air, arms flapping and all."

Seriously can someone explain the angel kids ?
Why does he spit when he stands on the boat?
And what's with the jumping troll??

Enjoy this classic!
