And speaking of Econ, here's Nobel Laureate Paul Krugman at 2009's ceremony wearing a bra as an emergency facemask:

And here he is as part of the largest group of Laureates to remove a sword from someone's throat:

The Nobel Laureates involved:
Rich Roberts - Nobel Prize in Physiology/Medicine, 1993
Wolfgang Ketterle - Nobel Prize in Physics, 2001
Dudley Herschbach - Nobel Prize in Chemistry, 1986
Paul Krugman - Nobel Prize in Economics, 2008
Roy Glauber - Nobel Prize in Physics, 2005
Frank Wilczek - Nobel Prize in Physics, 2004
Martin Chalfie - Nobel Prize in Chemistry, 2008
William Lipscomb - Nobel Prize in Chemistry, 1976

CRITERIA TO BEAT RECORD:
- sword swallower must be a legitimate sword swallower officially verified and recognized by the Sword Swallowers Association International
- sword must be a solid steel non-retractable sword with a blade at least 15 inches in length
- Nobel Laureates must be recognized bonafide Nobel Laureates who have actually been awarded an official Nobel Prize.

I'm beginning to suspect he is something of a ham.
In addition there is video of the awards and their version of TED Talks, the Ig Informal Lectures up the river at MIT.

There are also the 24/7 Lectures:

Each year at the Ig Nobel Prize Ceremony, we invite some of the world's top thinkers to tell us what they are thinking about.

            Each 24/7 Lecturer explains their topic twice:
                  First, a complete, technical description in 24 seconds
                  Then, a clear summary that anyone can understand in 7 words

But I didn't see this years contributions. Here are a couple from the 2017 vintage:

Topic:  Bots

Lecturer:  Aleksandra Przegalinska    (Professor of Artifical Intelligence and the Philosophy of Technology at Kozminski University In Poland, and a researcher at MIT)

In 24 Seconds:  "We presented a study of human-bot interaction based on an experiment that consisted of two parts: measurement of psychophysiological reactions to chatbot users and a detailed questionnaire that focused on assessing willingness to talk to a robot or chatbot. Our particular focus was on the "Uncanny Valley" effect, and in the experiment, we juxtaposed the EDA channel with a digital input channel, and the data indicated a very strong positive correlation between the uncanny valley effect and negative affect evaluation. " [Time called by the Referee]

In 7 Words:  "Robots that talk are perceived as stupid"

[Actual Number of Words Used:  7]

When in the ceremony video:  0:38:00

Topic:  Uncertainty

Lecturer:  Eric Maskin    (Nobel Laureate and Professor of Economics at Harvard University)

In 24 Seconds:  "Uncertainty is the heart of economic life. What do oilmen, poker players, and bond traders have in common? Oilmen drill their wells, poker players look for tells, and traders time their sells in order to exploit other people's uncertainty. A party who does this well will earn a profit. Then the other parties will cry if they want to." [Within the time limit]

In 7 Words:  "Uncertainty is the only sure thing - perhaps"

[Actual Number of Words Used:  7]
