When I am done, I am going to put in some booby traps

Speaking of booby traps..
I read this in a book recently.. I loved it:

Take a cheap Saturday nite special, take one round for it and pull out the
bullet from the shell and dump out the powder.
Replace it with C4 and push the bullet back in and reload..just the one
round
When the dirtbag that steals it tries it out...BOOM !

You get to track him by the blood trail from the 'stump'
