Oof - that had to hurt.  Ten-Tec has a nifty means to ground the anode 
supply by way of a piece of sheet metal attached via bolt in chassis 
which can be rotated and rest atop the HV post.  Gravity holds the metal 
in place across the HV post ensuring a fairly reliable means to help 
prevent accidental HiPot testing.

When I was a young pup in school I used to charge up large filter caps 
salvaged from old color TV sets - then place them on a table and wait 
for a hapless victim to discover what they were.  It was more satisfying 
to be out of view but within earshot of these "Tesla Discovery" events.
