Oil Drain Plug....RTV!

I have seen some with threads so jacked it broke the nut for the plug right off the inside of the pan trying to get it out.
Damn! now it's loose but can't be tightened or removed either one.
(Used to be..)Common on 200-300,.000 mile imports,with Jiffy Lube jockeys overtightened the drain pan plug,every time...
