Hey Cab - If that fitting is cast, there's a very good chance he can bust it with a hammer. I think it's forged - and if it is forged, busting it with a hammer is going to be tough.

If pipe wrenches plus cheaters aren't doing the job, I would heat the fitting until it glows. That's if I felt good about protecting the stud and wall behind it. If heat seems like a bad idea - you can saw it off.
