get one of those lizards from the jungle that has a perma lock poison bite, you know the ones that bite you and about 3 hours later you turn green and topple......then they let go....and start eating you...then put a little collar on it with a tag saying something like "my name is mike and I eat tool theives" just so they can see the message before they black out.....put it in the tool box.....they open it.....chomp....
Your nuts !
