Nah, Jack didn't surpass Walt at all. Each dog has it's own personality. Walt was a classic. As for Jack--
Remember, years ago we got him on "sale" at the dog adoption place.

Yup, he was the "featured dog of the day" which sounds a lot like where I work. (HR will post on their web site, a "job of the day" to give it more prominence. But, those of us on the "inside" know that the job of the day includes all the ones that they can't fill, because no one wants those jobs!)
Jack is special needs, twisted, and dysfunctional on all levels--that's why he fits in so well with us!
