Part of our series on odd beauty contests.
The first (?) contest was apparently held in 2017.
Read about it here.
What appears to be the home page has lots of pix and even videos of the 2018 contest. But I cannot find reference to competitions for 2019 or 2020.
A recent issue of the Dutch journal
Tijdschrift voor Psychiatrie (Journal of Psychiatry) reports on the case of a woman who believed she was a chicken. From the report (via Google translate):
Patient A, a 54-year-old woman, consulted the emergency department with her brother for acute attacks of deviant behavior, expressing the belief that she was a chicken and displaying behavior reminiscent of it.
Clinically, we saw a lady profusely sweating, trembling, blowing her cheeks and displaying stereotypical behavior in which she seemed to imitate a chicken, such as clucking, cackling and crowing like a rooster. After ten minutes, she seemed to tense the muscles for a few seconds, her face flushed and she did not respond for a short time. These symptoms repeated at intervals of several minutes, between which anamnesis was possible. The patient's consciousness was fluctuating, attention was hyper-reactive and the patient was disoriented in time and space. Her memory could not be tested objectively, but she could adequately tell her history.
She said she had barely slept since five days and wandered barefoot and dressed in a dressing gown on the street at around 4 a.m. the previous night. A general feeling of unwellness had been present for several days, as well as a strange feeling in the limbs, as if they no longer fit her body and flapped uncontrollably. The patient expressed the thought of being a chicken and that they had been forgotten to roost her.
Patient's brother added that he found her in the garden in the same condition as we saw her now. Between that moment and the registration with us, the bizarre behavior in attacks occurred.
The researchers note that clinical zoanthropy (the belief that one has turned into an animal) is an extremely rare delusion. Apparently there have been only 56 cases of this reported between 1850 and 2012. Some of the animals people believe they have become include "a dog, lion, tiger, hyena, shark, crocodile, frog, bovine, cat, goose, rhinoceros, rabbit, horse, snake, bird, wild boar, gerbil and a bee."

I posted about Gaylia Davis, aka 'Miss Sewer Cleaner,' back in 2016. At the time I wondered what became of her. And did being Miss Sewer Cleaner boost her career? Recently I was contacted by her granddaughter, Rose, who supplied an answer, which is appended below, beneath the original post. Not surprisingly, it doesn't seem as if being Miss Sewer Cleaner had much, if any, impact on her career. But she certainly went on to have an interesting life regardless.
October 1951: Gaylia Davis, 17, was awarded the title "Miss Sewer Cleaner of 1952." She reflected philosophically that, "It may be a soggy title but if it helps my career I don't care."
I can't figure out what became of her after 1951. So it's hard to know if it helped her career or not.

Update: Below is the text of the email from Gaylia's granddaughter. And below that are some pictures she also sent along.
Gaylia Davis ended up leaving Detroit and following her mother (who had previously divorced Gaylia’s strict Preacher father- he founded a church in Detroit) to Miami! Gaylia’s mother, Ethel, came to Miami Beach to start a radio show! Anyway, Gaylia met a young Cuban man named Ernesto Gavalda. They were both performers and dancers and did variety shows in both Miami and Cuba. Gaylia also traveled for a bit with the Barnum & Bailey’s Ringling Brother’s Circus. She was one of the Amazonian models that rode regally on the elephants.
She (all American girl) and my (Cuban) grandfather (a la I love Lucy) ended up getting married here in Miami Beach and having 6 kids together. The only daughter (the rest are boys) they had, Debbie, is my mother. She was born and raised in Miami Beach. We are still in Miami to this day.
Gaylia ended up becoming a local fixture on the streets of Miami Beach as she decided to live as a homeless evangelist. She was called “Mother Mary” or “the Bible Lady” by locals.
I remember wanting to visit her as teen and having to ask strangers if they knew where the “bible lady” was. They’d point to some park bench or mumble a street name and I’d find her with a tattled Bible in hand and preaching to any passerby.
Gaylia only recently passed at the end of 2018. Up to her dying day, she was still quick witted, humorous, tough, and of sound mind. She could still talk politics, history, and culture.
She has always been an enigma to me and even more so now as I get older myself.
Anyway, thanks for listening and asking!
