Yet another way to stress players...

[General Pain]

ask them to roll a couple of these dices... http://www.etsy.com/view_listing.php...ng_id=26467918

...then consult a non-existing table, while saying stuff like:
-ohh really
--sad so sad...
-allmost lucky that time...
-atlast I can use my .....(insert word like flamethrower or untested handgrenades
- ...thank god....
-...guess it could have been worse....

Another trick I use is handing out a piece of paper with the note (this is just to stress the other player) to a random player

happy gaming evryone
