Apparently, at least in the WCW, there is a line. No murder fantasies.
UPDATE: I've been informed the WCW doesn't exist and this dude was only fired from some radio gig. Still, if you hire a former pro wrestling commentator to do a radio gig, don't you kind of expect him to say really insensitive things? Maybe Hardcore Sports can give the guy a call. From what I can tell an ability to drop the F-Bomb every three seconds is the biggest job requirement there, so he'd fit in.
