I'm writing an, um, novel (swallow), so I have soooooooooooooooooooooooooooooooooo many, many, many, many questions. I guess I'll start with this one:
What words or phrases might devout Jews substitute for such typical American English interjections as, "Holy [whatever]!" or "G-d damn it!" or "Dammit!" or "Hell!" or "Heavens!" or "Jesus Christ!" or "Jeez!" ... and so on? I presume exclamations such as, "By HaShem!", while arguably avoiding the Name of G-d, still violates the spirit of the First Commandment.
