the rabbit died

The woman to whom we are referring is pregnant; the pregnancy test was positive. (From an early pregnancy test developed in 1931 in which the urine of a woman thought to be pregnant was injected into a female rabbit; if the woman was pregnant, the rabbit's ovaries would react. A common misconception at the time was that the rabbit would die if the woman was pregnant, hence the expression.) I saw Carol shopping for maternity clothes in the mall the other day. I guess the rabbit died! Honey, the rabbit died! It looks like we're going to have a baby!
