That's pretty messed up. I'd say flush it as well as you can and try to get a clone. Maybe transplant to new soil if that's what you're using. Basically what faithlessxxx said. Bummer. That really sucks man. Go put ex-lax in his beer or something. lol But on a serious note, if he's willing to do this, I'd be very wary of him calling someone to come take a look at them. Be safe.
