An absolutely delightful expression from Arkansas is, “I ain’t got a dog in that fight.” I (Randy) have used it in Florida as a powerful administrative tool to indicate that (1) the issue at hand is not an integral part of my area of responsibility; (2) this is a messy problem with a lot of upset people; and (3) I could get hurt if I get involved and I am not invested sufficiently to justify the risk. Stating this propositionally takes longer and is often less effective.
