We show that every externally definable fsg group in an NIP structure M is definably isomorphic to a group interpretable in M. Our proof relies on honest definitions and a measure theoretic group chunk theorem reconstructing a hyper-definable group from a generically given group operation. We also discuss some preliminary results and directions on externally interpretable fsg groups, and on going beyond fsg.
