I’d be in serious trouble there.
Spent my first 10 years in NYC and knew lots of Jews. Then was in publishing biz, and publishing houses. mostly run b¥ Jews, are centered there .Was in and out of town several times a year. I use a lot of Jewish expressions and Jewish people often thought I was Jewish too
These idiots should all “drop dead in good health”’
If you have an enemy, Yiddish expression is “May all your teeth fall out but one.”
