Here’s a story that doesn’t exactly fit the title (in fact I was going to start a new thread but decided to post it here anyway).
This happened a number of years ago. Apparently there were 2 high school girls on a city bus in NY , when suddenly quite a “large” woman got on the crowded bus and stood near the girls. It was quite uncomfortable and cramped. One said to the other “he shemayna k’mo parah”. The ride continued. A few stops later, the woman was ready to get off, when she turned around to the girls and said “mooo”! I can only imagine how shocked and embarrassed those girls were!
