Jim,- your comment begs the questions, are you an Adam Sandler fan, (whoever he is), and do you have a seafood allergy?
If you read Jim's post and seriously came to those conclusions then that explains a lot.
His statement was classic dry British humor and I do not for one second believe that it went over your head (or that you don't know who Adam Sandler is).
Jim does not eat fish or any seafood of any type. I jokingly say it is professional courtesy but it is a personal preference of his. When I visited him in Calif. one of the topics which came up (since I love food of all types) was his eating preferences. The catalogue of things that Jim will not eat is legion.
As for Adam Sandler I leave that to others to explain.
