Abstract: 
Inspired by questions about the HOD dichotomy, we consider how and in what manner we can force HOD to be "far from V". Our initial result is an equiconsistency in ZFC between a model with a proper class of measurable cardinals and HOD and V agreeing on the cardinals yet disagreeing on the cofinality of a proper class of cardinals.
