Porsha Stewart had her Jessica Simpson chicken of the sea moment on the Dec. 22 episode of The Real Housewives of Atlanta. But her lapse had much more historical context than any fish-or-fowl mix up.
The 32-year-old visited a landmark church with holes in the floor, which were used for ventilation on the Underground Railroad (as led by Harriet Tubman) during the pre-Civil War era. The group's tour guide said they still don't know how groups of escaped slaves managed to get in and out from the crawl space.
Stewart, whose great grandfather was civil rights leader Hosea Williams, quickly piped in with her thoughts on the matter.
"Well, there has to be an opening for a railroad at some point," she said. "Because somebody's driving the train. It's not electric like what we have now."
Her costars looked on in shock and irritation as their newly-single pal continued to talk about the historical system as if it was actually working railroad.
"Really? Like you really thought it was an actual train that took them through?" Cynthia Bailey said in her side interview.
Former pageant queen — and Stewart's biggest nemesis — Kenya Moore found it to be more offensive than shocking.
"It's almost hurtful to me to watch her be so dumb," Moore said in her private interview.
Naturally, sassy NeNe Leakes had some thoughts of her own on Stewart's flub.
"Ding dong! He's not talking about put baby sis on the train or on the damn public bus," she exclaimed.
Stewart has not yet commented on her on-air faux paux, but her onscreen nemesis, Kenya Moore, took to Twitter to continue discussing the topic.
"When her grandfather fought 4 civil rights that she bragged about, to not know that there wasn't a literal train! #freedomwasnotfree #RHOA," she wrote.
