Wellington woman Bailey Price sold the right to tattoo her behind on Trade Me this year.
A posterior tattoo canvas, erotic eggplant, dead cat handbag and a desk chair of fertility have all made Trade Me's greatest hits of 2016.
The online auctions all either ranked in the site's honourable mentions for exceptional creativity or the top 10 most viewed, which wracked up almost 800,000 views between them.
The online auction site's spokesman Logan Mudge said they were constantly amazed at the "endless creativity and entrepreneurial spirit" of their members.
"Sometimes they hit a nerve with the public and make the ordinary extraordinary."
Some auctions "just have a certain something" which captured imaginations because they're weird, controversial, often borderline in taste terms, Mudge said.
Wellington woman Bailey Price sold a 9cm x 9cm space on her behind for $6500 with a mysterious buyer named Paul winning the honour.
As it turned out, Paul is the cousin of American musician "Sir" Ivan Wilzig.
The 20-year-old will be flown out to Miami next year to get either 'SIR IVAN's "IMAGINE" on iTunes' or 'SIRIVAN.com' beneath a rainbow inked on to her posterior.
"It was weird, a little bit cheeky and the bottom line is Bailey was great with the Q&A and at drumming up a bit of publicity for her auction," Mudge said.
Another controversial auction which racked up more than 55,000 views was the dead cat handbag.
The cat had been in taxidermist Claire Hobbs' freezer for a year before being fashioned into a rather unique handbag which set tongues wagging around the world and clocked up more than 160 complaints.
However, because they allowed other taxidermy items to be sold they let the auction run - eventually selling for $545, a third of what Hobbs was hoping for.
"On the other side of the coin lots of people thought it was cool and interesting and it found a new home with a very keen buyer."
An erotic eggplant on auction also had a happy ending, selling for $115.
As did a potato in the shape of a bottom collecting an enormous number of views and interest, Mudge said.
