No. 2 - Peeing on Rabbits
Let's talk about Phaedra's Phoolproof Pregnancy Test -- according to Phaedra people used to give a rabbit a woman's urine to test if she's pregnant. If the rabbit dies, you're with child.
Now I hit the internet for answers. Wikipedia tells me that this was indeed a thing, but there was a common misconception that the rabbit just died if the urine was from a pregnant woman. Scientists had to check to see if the hormones affected the rabbit's ovaries (meaning the woman was pregnant), but to do so, the rabbit would die.
So listen up: don't go giving rabbit's your pee to test for pregnancy! Stick to the stick.
