Tom Thwaites had special prostheses made so he could walk like an animal.
The spoof awards, which are not quite as famous as the real Nobels, were handed out during their annual ceremony at Harvard University, US.
Other studies honoured during the event examined the personalities of rocks, and how the world looks when you bend over and view it through your legs.
On the surface, all the celebrated research sounds a bit daft, but a lot of it - when examined closely - is actually intended to tackle real-world problems.
And nearly all of the science gets published in peer-reviewed, scholarly journals.
It is unlikely, though, that the German carmaker Volkswagen will appreciate the point or humour of the Ig Nobels.
The firm has been awarded the chemistry prize for the way it cheated emissions tests.
Clearly, the practice is fast-becoming a national trait.
Mr Thwaites concedes his effort was initially an attempt to escape the stress of modern living, but then became a passion.
He spent a year researching the idea, and even persuaded an expert in prostheses, Dr Glyn Heath at Salford University, to build him a set of goat legs.
Fascinating, if a little bizarre on occasions, was Mr Thwaites' verdict on the whole venture. He developed a strong bond with one animal in particular - a "goat buddy", but also very nearly kicked off a big confrontation at one point.
"I was just sort of walking around, you know chewing grass, and just looked up and then suddenly realised that everyone else had stopped chewing and there was this tension which I hadn't kind of noticed before and then one or two of the goats started tossing their horns around and I think I was about to get in a fight," he told BBC News.
The American science humour magazine, the Annals of Improbable Research, is the inspiration behind the Ig Nobels, which are now in their 26th year.
Thursday night's ceremony was reportedly as chaotic as ever, with audience members throwing the obligatory paper planes while real Nobel laureates attempted to hand out the prizes.
The full list of winners announced at Harvard's Sanders Theatre:
Reproduction Prize - The late Ahmed Shafik, for testing the effects of wearing polyester, cotton, or wool trousers on the sex life of rats.
Economics Prize - Mark Avis and colleagues, for assessing the perceived personalities of rocks, from a sales and marketing perspective.
Physics Prize - Gabor Horvath and colleagues, for discovering why white-haired horses are the most horsefly-proof horses, and for discovering why dragonflies are fatally attracted to black tombstones.
Chemistry Prize - Volkswagen, for solving the problem of excessive automobile pollution emissions by automatically, electromechanically producing fewer emissions whenever the cars are being tested.
Medicine Prize - Christoph Helmchen and colleagues, for discovering that if you have an itch on the left side of your body, you can relieve it by looking into a mirror and scratching the right side of your body (and vice versa).
Psychology Prize - Evelyne Debey and colleagues, for asking a thousand liars how often they lie, and for deciding whether to believe those answers.
Peace Prize - Gordon Pennycook and colleagues, for their scholarly study called "On the Reception and Detection of Pseudo-Profound Bullshit".
Biology Prize - Awarded jointly to: Charles Foster, for living in the wild as, at different times, a badger, an otter, a deer, a fox, and a bird; and to Thomas Thwaites, for creating prosthetic extensions of his limbs that allowed him to move in the manner of, and spend time roaming hills in the company of, goats.
Literature Prize - Fredrik Sjoberg, for his three-volume autobiographical work about the pleasures of collecting flies that are dead, and flies that are not yet dead.
Perception Prize - Atsuki Higashiyama and Kohei Adachi, for investigating whether things look different when you bend over and view them between your legs.
