Ever thought your weird or gross habits could be a goldmine? It turns out that the stranger your routine is, the fatter your wallet might get.
Believe it or not, there’s a growing economy built around the bizarre—and it’s booming. From selling used bathwater to cashing in on toenail clippings, people around the world are flipping their so-called “disgusting” habits into five and even six-figure incomes.
According to a 2023 Forbes report, the global gig economy has reached a staggering $455 billion, with an increasing percentage attributed to unconventional and niche markets.
It’s not just about attention—it’s about supply and demand. And when there’s a fetish, curiosity, or niche market attached to a behavior, people will pay. Sometimes a lot.
Scroll down to see 13 cringe-worthy, eyebrow-raising, yet shockingly profitable ways people are cashing in on what most of us would never admit to doing.
Selling Your Poop

Fecal donation sounds similar to something out of science fiction, but it’s becoming a recognized medical practice. People often need healthy stools for fecal microbiota transplants (FMT), mainly to help treat Clostridioides difficile infections, also known as C. diff.
Some medical facilities spend up to $250 weekly for five samples, which costs $13,000 annually. Because donors have to pass strict health criteria, this method is reserved for a few people. If you’d like to start, try contacting organizations like OpenBiome and others that are conducting research studies on FMT.
Gaining Weight for Science

Earning money by eating more might seem significant, but there is more to it than that. Those researching obesity, diabetes, and hypertension may select participants who then gain weight under scientifically planned conditions. In one study, people received $3,500 to add 1,000 extra calories to their diet by eating fast food daily.
The compensation may be reasonable, but again, expect some physical and emotional problems during your research. Sometimes, someone pays for their indulgence by facing discomfort shortly afterwards.
Competitive Eating

If you’ve ever watched someone get through many hot dogs on TV in just a short period, that’s an example of competitive eating. With dedication and hard work, Joey Chestnut and others turned eating contests into true careers and have made thousands from sponsors and contests.
Participants at Major League Eating events also eat pizza, chicken wings, and hamburgers. Did You Know? Joey Chestnut once ate 32 double-patty burgers in just 38 minutes.
Burping for Cash

It is possible to earn money just for belching on cue. Several soda businesses and advertisements have asked people who can belch well to be considered for commercial projects.
Casting directors wanted to pay $750 for a day’s work and throw in free snacks to make us burp! Remember, casting sites often have creative opportunities, so check regularly.
Regurgitation Acts

Many people find swallowing and bringing back objects nauseating. Still, for Stevie Starr, it’s his immense talent. Starr has gained fame under “The Professional Regurgitator” for consuming billiard balls, coins, and live fish, then throwing them out unharmed.
His unique talent has allowed him to feature on talent shows worldwide. Individuals in this job can earn thousands at each performance.
Selling Your Spit

Your saliva’s value is enough to be marketed. DNA research and ancestry businesses, such as 23andMe and DNASimple, offer people compensation of $50 to $200 for providing a saliva sample.
Scientists use your genetic information to further health and ancestry studies. Through DNASimple, various studies can find the participants they want.
Dog Poop Cleanup Services

Communities that have many pets are finding “pooper scooper” services increasingly popular. Many individuals and small businesses provide subscription services to clean up your yard after your pet.
A well-trained entrepreneur might get paid $40 to $80 for each job and earn much more with a consistent list of customers. Try local advertising or sign up on platforms like TaskRabbit to gain your first clients.
Snake-Inspired Toilet Cleaning

Unclogging and cleaning toilets filled with unclean refuse technically comes under plumbing, but it’s work that not everyone wants to do. You could earn a lot if you’re brave enough and own a plumbing snake.
One man said he could make $400 daily using special toilet-cleaning tools. To work more efficiently, he recommends using a high-quality electric plumbing auger.
Selling Feeder Roaches

If you like creepy-crawlies, making money by breeding and selling cockroaches is surprisingly easy. Although I have no experience breeding these feeder insects, experts say that a garage operation led one breeder to earn hundreds of thousands of dollars annually.
If weird smells do not disappoint you, you can save money and get great results. You can market your product by joining local pet stores and connecting with members of exotic animal forums.
Selling Breast Milk

A unique group of people is willing to pay for human breast milk. Lactating parents can make some extra money by selling additional breast milk. People who cannot breastfeed and bodybuilders are examples of buyers included in this analysis.
Fentanyl dealers can make between $500 and $1,000 a month, and the price for an ounce is often $2 to $5. Only use platforms that ensure buyers and sellers are trustworthy, for example, Only the Breast.
Food Taste Testing

Your favorite snacks and meals must be tested before becoming available in stores. Food businesses need to taste and evaluate new foods on an ongoing basis. When you eat the samples, you will likely taste wonderful and unappetizing things.
Usually, you’ll be paid between $25 and $50 per session, but some testers make more for particular sensory panels. Work for companies, including Matrix Sciences or local market research groups.
Rent-a-Friend Services

Be a friend—you can rent! RentAFriend is a website that lets you find someone to hang out with or meet. Most people charge between $20 and $50 an hour, so it’s a good way to earn cash while meeting new people.
A few experts might receive extra cash if they provide excellent service.
Reviewing Weird Websites

Website testing becomes different when examining odd or disturbing sites. A few companies enlist staff to review unusual, possibly distressing, online content.
Though it takes some courage, moderators get paid a lot for their work, with most starting at more than $20 an hour. Although this work helps online safety, you may come across disturbing information.
Key Takeaways

Earning from non-traditional jobs is real and not simply unusual stories—they’re innovative techniques people can try. For example, selling breast milk is much more profitable than people think.
A report from Global Industry Analysts notes that more people are now buying breast milk, mainly for use in donor banks and researching alternative ways to feed babies. Consistent donors often make thousands of dollars by donating milk.
Using what makes you different can help you succeed in some unique markets. For example, well-known burp artists using YouTube and TikTok earn money via views, ads, and sponsorships.
Influencer Marketing Hub reports that the average income for content creators on YouTube from ads is $18 for every 1,000 views. This means people with many viewers or subscribers can earn noticeable money. Such examples demonstrate that being different, informed by niche preferences, and using new technology can earn people money in uncommon ways.
