It's not on https://en.wikipedia.org/wiki/List_of_Ig_Nobel_Prize_winners .

However, Karl Kruszelnicki did receive Ig Nobel Prize for his research on belly button fluff.

This was from the BMJ Christmas issue - every year they publish a 2-week special full of nonsense like this. As it happens, 4 of the papers in BMJ Christmas Issues have gone on to win Ig Nobels:

- Effect of ale, garlic, and soured cream on the appetite of leeches (winner 1994)

- Magnetic resonance imaging of male and female genitals during coitus and female sexual arousal (1999)

- Sword swallowing and its side effects (2006)

- Pain over speed bumps in diagnosis of acute appendicitis (2012)

Didn't publish. As far as I know, the Ig's are for published research only.
