Science can be weird. Your goal may be to unlock the mysteries of how the human body develops, but you find yourself counting nose hairs in dead bodies to see if there are more hairs in the left or right nostrils. How does one obtain a grant for that?
The annual Ig Nobel Prizes were awarded last night in an online ceremony to researchers who published studies concerning the sexual activities of anchovies, hi-tech toilets, people who talk backwards, and other science that makes you laugh, and then makes you think. These prizes are sponsored by The Annals of Improbable Research, and co-sponsored by the Harvard-Radcliffe Science Fiction Association and the Harvard-Radcliffe Society of Physics Students.
Each winner this year received a .pdf document that can be printed and assembled to make a three-dimensional trophy, and a ten-trillion dollar bill from Zimbabwe. The prizes were bestowed by a line-up of real Nobel Prize winners: Frances Arnold (chemistry 2018), Marty Chalfie (chemistry 2008), Peter Doherty (physiology or medicine 1996), Esther Duflo (economics 2019), Jerry Friedman (physics 1990), Wolfgang Ketterle (physics 2001), Eric Maskin (economics 2007), Ardem Patapoutian (physiology or medicine 2021), Al Roth (economics 2012), Rich Roberts (physiology or medicine 1993), and Barry Sharpless (chemistry 2001 and chemistry 2022).

Unfortunately, the original paper is paywalled, but I was dying to find the results. I found this:
The research team counted the nose hairs of about 20 cadavers and found that on average there were 120 nose hairs on the left side and 112 on the right side, with slightly more on the left side. We also found that hair grows in front of the nose and only grows to a height of 0.81 to 1.035 cm.

The theme of the 2023 Ig Nobel ceremony was "water," although that had little to do with any of the prize-winning research. There was, however, a production number with several songs and no plot that had something to do with water. Here is the ceremony in its entirety.
