I worked with a guy who was in the AAF in WWII. He told me a story that I’ll try to remember. There were five or six of them on a late, nasty night in England. As I recall, he said it was extremely stormy. One guy braved the storm to get some food. He came back after a while and apologised to the one Jewish guy, ‘I’m sorry. All they had was ham sandwiches.’ The Jewish guy took one of the ham sandwiches, lifted the top slice of bread, and pronounced, ‘Ham nothing! That’s fish!’ And he ate the sandwich.
Isn’t there an exception in Jewish doctrine that allows people to deviate from the rules in order to survive?
(And is shark kosher?)
