I saw most of it (well, nothing much happened in the beginning, so I "scrolled forward"). But when it actually started, it was a lot of fun. I loved the Intelligent Designer (of clothes) and the Astrophysicists! The Designer asked the Astrophysicists how much fabric she needed to sew a dress for the universe (which appeared to be vaguely feminine), and how she should cut the cloth to fit the general shape of the universe.
I loved the research that seemed to prove that the Eiffel Tower looks smaller if you watch it while leaning to the left. Several prize-winners, both "Iglies" (Ig Nobel winners) and "real" Nobel laureates (I loved that several "real" Nobel laureates took part in the ceremony) lined up on stage and looked at a model of the Eiffel Tower while leaning to the left!
I also loved the research that proved that chimps can recognize a lot of other chimps by the appearance of their rear ends! Since the average human backside-identification skill is probably not up to the one in chimps, the scientists described their research as proof that chimps are, in some respects, mentally superior to humans!
There were also other references to this particular part of the human body. One group of prize winners had worried about the fact that the human rectum contains gas (as we all notice when we break wind), and since some medical examinations require doctors to put instruments up the patient's rectum, there is a very remote but not non-existing chance that something might set the gas alight and cause it to explode, with most dire consequences for the patient! Talk about spontaneous combustion from inside! The prize-winning Ig Nobel winners have found a method to make sure that endoscopy will never make the gases in the rectum explode, and that is certainly a boon to humanity!
To stay in this particular vein, I think my favorite part from the entire ceremony was a man delivering a 24/7 speech about whether arsenic-based life is possible. He had 24 seconds to give a full technical description of his topic, and then he had to explain it so that everyone understood it in only 7 words. During his 24 seconds, the scientist explained that arsenic might conceivably form compounds called "arseholes", and then he finished his lecture off with these 7 words:
"Only arseholes believe arsenic can support life!"
This was great fun, and it made me think a little, too! Thanks to bystander for posting it.
