A man paid a woman $5,000 to wear her underwear for three weeks without washing it.
The 21-year-old woman, known only as Lady Kitten, said "the money was too good an opportunity to pass up," Cosmopolitan reports.
Even though she "felt really disgusting," she went nearly one month wearing the same underwear every day.
"Luckily I live by myself and tried to stay indoors for most of the three weeks, so no one could notice," the college student explained, adding that she plans to use the money for school.

While the request may seem unusual, it's not too far off other orders Lady Kitten receives.
The woman says she regularly sells her used underwear through Sofia Gray, a website that allows users to sell their worn panties.
Founded in 2015, the service allows people to upload and purchase used underwear anonymously for prices ranging from $20 to thousands.
She explains she stumbled upon the website after watching Netflix show "Orange Is The New Black."

In the show, the character Piper Chapman sells inmates' panties.
Curious to see if this was a legitimate thing, Lady Kitten researched online. Sure enough, it was.
"I saw that some girls were making good money from this, so I thought I'd try it out," she said.
In the past six months, she says she has earned $4,000.
"I try to list three or four pairs each week, although I can get a bit lazy," she explains.
Her most recent, the $5,000 pair requested by a customer she's worked with before, is the biggest sale the website has ever seen.
She explains she has built a relationship with the anonymous customer. They know of their hobbies and interests, but unlike in dating, the connection is primarily about the underwear.
While selling used panties can apparently be lucrative, it comes with health risks.
"There's certainly an increased chance of yeast infection and of bacterial vaginosis, which is an imbalance of the usual bacterial environment in the vagina," says Dr. Alyssa Dweck, a gynecologist based in Westchester County, New York, and an assistant clinical professor at Mt. Sinai School of Medicine. "These types of bugs trend to thrive in warm, moist dark places. Three weeks without taking them off are certainly going to fit that bill ... Especially since there's no aeration in that area."
