Jewish people say beaver

I’m not sure if this qualifies as a BLM sighting, exactly, but I think it’s pretty interesting so I’ll post it. This past week I was in NY and my mom made me go to took me to the Museum of Jewish Heritage. There were lots of, you know, exhibits and stuff, but one thing in particular really caught my eye. It was a really old Yiddish/English dictionary that a Jewish individual had brought with him when he imigrated to America decades ago. The dictionary was propped open behind a piece of glass, opened to a random (I assume) page. And do you know what the first word in the second column was? BEAVER.
