Here's a true Jews/juice event that once happened.
On my second honeymoon, my new bride & I took a cruise to Alaska. Glacier Bay was all that, the glaciers were calving big time. Our table-mates on the cruise were a couple where the guy made his own daughter's wedding dress, complete with lace, and his wife was an attorney who worked on the Howard Hughes estate; the other couple was Leo and Myrna Goldbaum from New Jersey. I usually ordered a bottle or two of wine at the evening meal, offering each table-mate a glass or two if they were inclined. Leo Goldbaum never accepted my offer of wine, calling it "ignorant juice," (a point well taken).
Later at a friend of my wife's, a mixed couple of Guatamalan and Jewish mixture, I was telling the story of our honeymoon cruise, and brought up the subject of ignorant juice. My host seemed taken aback, that I'd said my cruise mate called wine ignorant juice. In reality he'd thought I'd said "ignorant Jews" because of the phonetical similarity. His wife called him paranoid, and we all had a good laugh.
