When I was in the M.E. the locals would wave their hand in front of one of those green scorpions to get its sting up, then, with the other hand, come in from behind and grab the sting.
The scorpion would then be thrown in the ring with one Camel spider - loads of them about - and fight to the death - place your bets!
Did you know that scorpions glow a weird blue in the light of a UV / white LED torch?
