Nope. It’s an attempt at Lunaspeak for “The rabbit died” (meaning, “I had a pregnancy test done”). Since only reason to admit you had one was to let people know ahead of time what would eventually become very obvious, it became shorthand for “I’m pregnant” (unless you were a guy, in which case it meant you got someone else pregnant).
 
Even now with home pregnancy tests that don’t involve invasive surgery on animals, and a much more open discussion of how reproduction works, a pregnancy test is still called a “rabbit test” by some people, and the expression is also still in use.

Hey! EQD actually picked it up and added this drawing to the daily display of art! Cool! Finally!

So “Sister, the rabbit is dead” isn’t an X-Files reference?

I’ve saw that on squidbillies
 
did not know that was real

The rabbit test, an early pregnancy test that involved injecting potentially pregnant women’s urine into female bunnies, then seeing if the lapine ovaries reacted to a hormone that would confirm the woman’s pregnancy. Isn’t science fascinating?

@FanOfMostEverything  
what the fuck?

@Background Pony #A70B  
That saying bugs me, no pun intended. No matter what the outcome, the rabbit has to be killed in order to check the test results. Unless you know of a way to nonlethally extract bunny ovaries.

Spit take!

“We did warn our dear sister that her tea was hot.”

Seriously, though, this is such a perfect drawing that EQD would have to be out of their minds not to show it off.

“Sister, the rabbit is dead.”
 
PPPPHHHHHHffffffffftt!

“…You know I always thought you pretty hot.”
 
“Why yes, I did use poison joke in the tea”
 
“…And THAT’S when I realized I was in heat and I had to fuck the cake.”
