Mark Parisi of Las Vegas expects to take part in a study where he would have to sell one of his testicles in exchange for $35,000.

Mark Parisi revealed in a trailer for an upcoming episode of TLC’s “Extreme Cheapskates” that he will make the switch with an artificial ball in exchange for the cash.

The penny pincher also confessed to undergoing medical experiments so he could get free checkups, which can save him around $700.

It also meant he could wear the hospital scrubs, which saved on buying clothes and ensured he never had to spend a dime from his paycheck.

“When I was doing clinical trials … I would take a pair home, I would use them for daily work, exercise and for doing other clinical trials,” he said.

“Saved on laundry, cheap to clean, and they were free,” he added.

Parisi, who regularly participates in clinical trials, appears on an upcoming episode of TLC’s ‘Extreme Cheapskates.’

Mark, who has undergone several medical tests for money, said his friends were most terrified during the “Ebola” test.

“Everyone was panicked when my friend and I did this study. Never tested on humans or animals before,” he said, before adding, “It’s $5,000 for a week, so why would I not do it?”

Another study, for which he was particularly excited, sadly got cancelled at the last minute.

“This is a really good one,” he said of the “flatline” test.

“What they do is they stop your heart for one minute, but you still breathe. Stay there 14 days, pays $25,000. But the FDA kind of stepped in and stopped that,” he ended.
