Ruth and Sarah were walking along Kahaneman St. in Bnei Brak. Ruth says, “My son Lipa is getting married. He tells me he is engaged to a wonderful girl, but... the matchmaker thinks she may have a disease called herpes.”
Sarah ask: “Do you have any idea what this herpes is, and can he catch it?”
Ruth replies, “No, but I am just so thrilled to hear about Lipa’s engagement - it’s time he settled down. As far as the herpes goes...who knows?”
“Well,” says Sarah, “I have a very good medical dictionary at home. I’ll look it up and call you.”
So Sarah goes home, looks it up, and calls Ruth. “Ruth, I found it. No worries. It says herpes is a disease of the gentiles.”
Leo Rosten, is that you?
