This year's Ig Nobel prizes have been announced. It's kind of like the Nobel Prize, but for the weirdest and sometimes dumbest studies of the year.

The 2018 line-up didn't disappoint, here are this year's winners:

  • A study that found riding roller coasters can help you pass kidney stones.
  • A study that found chimps imitate humans about as well as humans imitate chimps.
  • A study that found wine experts can smell a single fly floating in a glass of wine.
  • A study that looked at how good saliva is at cleaning dirty surfaces.
  • A scientific paper called, "Colonoscopy in the Sitting Position: Lessons Learned from Self-Colonoscopy."
  • A study that found most people don't read instruction manuals.
  • A study that found that cannibals don't get a ton of calories.
  • A study that looked at why people yell and curse while driving, and measured the frequency of their screams.
