The super X-RATED Trade Me listing is CRACK UP!

A hilarious listing has popped up on Trade Me and it is not only making people blush, but it turns out it is for a surprisingly good cause.

In the fresh produce section, a seller is advertising a "veraciously virile kumara" and it seems a lot of people are interested in the comedic shaped food.

While the price of your average kumara is around $5 per kg, the bids for this x-rated vegetable have already reached $225 (at time of publishing).

And it's not just the photos that are making people giggle. The listing’s description written by Auckland Trade Me seller mikew4 - who is set to donate the profits of the auction to the Prostate Cancer Foundation of New Zealand - is also very amusing.

"I ask you this; How in the name of natural science did my urban vegetable garden in the picturesque hamlet of Waiuku produce such a splendid spectacle of virility as this magnificent Kumara?" the listing reads.

"Just look at the unnecessary level of detail that nature went to ... Why does it have veins? Why the graceful curvature? What ungodly power does this pulsating purple war hammer hold within its rigid core? Who placed it in my soil? Odin himself?

"Is the great architect now sitting back in their chair proudly admiring their work with the satisfied smile of a 13-year-old kid who has just mastered the art of phallic drawing in the back of their maths book?

"Whole civilisations of idol worshippers have probably sprung up in humankind's history for less provoking natural wonders than this Kumara. 

"If this was dug up in the mountains of ancient Peru it would be heralded as a sign of great fertility and prosperity for the coming seasons and would be hauled to the summit of a mountain by a hoard of devoted adorers to be sacrificed to the rising sun. 

"If you gave Michelangelo a bar of modelling clay and challenged him to come up with the most vulgar phallic representation of male genitalia that he possibly could, he would throw down his tools in despair if he saw what my Kumara patch just produced. 

"If his David statue had half the potency of this monstrous demon it wouldn't be on public display today and Goliath would have backed out of the fight real early on.

"If you buy this Kumara you are not simply buying a Kumara. You are buying prosperity itself. You are buying a wonder of the natural world & a pinnacle of botanic evolution. 

"I believe I have been gifted this botanic beast for a reason so am auctioning it off. Every dollar of this auction will go to the Prostate Cancer Foundation of New Zealand to help with their work. One day you or someone you know may need them."

The auction - which has been viewed more than 66,000 times - runs until 7.30pm this Friday and is sure to get a few more bids between now and then.
