There was a movie back in the 60's called "Born Losers", it was a "Billy Jack" movie that starred Tom Laughlin. Well, good old Billy Jack sticks his nose into someone else's fight and it goes sideways, legally, for Billy. Billy and a lawyer (I think it was a lawyer, it's over 50 years ago) were walking out the courthouse and lawyer says something like, "Go ahead and help someone else again". I've never forgotten that. The current phraseology is, "Not my monkey, not my circus", also good. MYOB
