Best unintentional Spinal Tap moments in metal.

Tyrant from Germany had a singer named Kermit and did this:

Scorpions at MOR Donnigton 1986 Klaus doing the human pyramid thing like this



Only to get hit in the side of the head by a plastic bottle that was filled with a very suspiciously yellow liquid and fall off. Horrible but kind if funny and very Spinal Tap.
