A man is planning to have a TESTICLE chopped off then sell it to scientists for £22,000.
Ballsy Mark Parisi will appear on a reality TV show undergoing surgery that will see one of his testicles removed - then replaced with an artificial orb.
He said: "What you do is you go in and you donate one of your testicles, they replace it with an artificial one and when you check out after 14 days you get a cheque for $35,000."
Mark, from Las Vegas, regularly enrols in clinical trials but says he is "anxious anxious and excited" ahead of this study.
Penny-pinching Mark will appear on the aptly named Extreme Cheapskates programme, showing on TLC in America on Wednesday.
The compensation for being a human guinea pig means he doesn't need to dip into his full-time salary - and he has an array of surgical scrubs to wear at home.
