Perhaps we can arrange some charver only warehouse parties. Ensure the doormen only allow the genuine "cheap argos gold ersatz-bling, shellsuit, trainer and baseball cap" wearing charvers inside. Once you got a worthwhile number in there, lock it up, and start pumping anasthetic in there.
Once they're all unconcious, take them off for intensive decharverification treatment...
If that doesn't work, simply pump hydrogen cyanide into the place, instead :-x
:oops: Did I really say that?
