I think Ne is what really makes ESTJ's bearable. My dad's got it down, you can tell when he tries to solve puzzles and such. At Cracker Barrel he always astounded me with being able to come up with like 3 different ways to solve those triangle puzzles. Or sometimes he'll go into goofy mode and just make up some random clever word-play thing.
Speaking of Si... this publicity shot for "Dexter", if you consider his background, seems very Si to me. My interpretation of it, anyways, is that all the little pieces from his childhood make up who he is today.
