I admit it, this mod is monumentally silly. It is something that SOMEONE should've done a long time ago however, heheheh.

If you're outside the underdark and still have the Light Gem, then you'll receive the Holy Hand Grenade of Antioch. Otherwise you can just console in MISC9R. Once you have the item, go kill a bunnyrabbit with it. The grenade will ONLY kill rabbits due to some bizarre cross-dimensional gesalt. 
If none of this makes sense or is funny to you, go rent some damn Monty Python ya' freak! ;)
