The rabbit done died

The topic of this ancient pregnancy test came up in Second Life, with most never having heard of it.

Wikipedia has an article, and within are the echos left by it in pop culture:

The rabbit test was featured in the episode of the television series M*A*S*H entitled "What’s Up, Doc". A rabbit (Fluffy) belonging to Radar O'Reilly was used to test for pregnancy in Margaret Houlihan. To assuage Radar, rather than killing the rabbit, Hawkeye Pierce performed surgery under anesthesia. When Houlihan later thanked Radar for the use of his pet, he responded that he was sure that she would have done the same for the rabbit.

The Aerosmith song "Sweet Emotion" refers to the test: "Can't catch me 'cause the rabbit done died."

Country singer Eric Church also references this in his song "Two Pink Lines" saying "these days the rabbit doesn't die"

In the BBC comedy The Vicar of Dibley, in a purposefully absurd variation of the rabbit test mixed up with home pregnancy test kits, Alice Tinker Horton tells the vicar she can't be pregnant because she "wee'd on a hamster" and it didn't turn blue.

In an episode of The Golden Girls, Sophia Petrillo claims that she believes she is pregnant. Her daughter's response is, "What happened? The rabbit died laughing?"

An independent short film titled Redemption Maddie centers on the idea of testing pregnancy with rabbits.

In Squidbillies, the rabbit test was used to determine Rusty's paternity. However, the rabbit died when Early's acidic urine "melted" the rabbit into an ooze, rather than as a result of the test procedure.

Billy Crystal starred in a 1978 movie Rabbit Test in which he became pregnant.

A collection of essays by Teresa Bloomingdale, columnist and mother of ten, bears the title I Should Have Known It When The Rabbit Died (1979). The title refers to an anecdote (1956) in which the rabbit used in her first pregnancy test died from jumping off the examination table, thereby shrugging off any responsibility for her ever-growing family.

In Philip K. Dick's novel The Game-Players of Titan, pregnancy is tested by biting a strip of "rabbit paper".
