An Ig Look Back: He Swallowed a Shrew

This drawing by artist Becky Moon celebrates the 2013 Ig Nobel Archaeology Prize, which was awarded to

Brian Crandall and Peter Stahl, for parboiling a dead shrew, and then swallowing the shrew without chewing, and then carefully examining everything excreted during subsequent days — all so they could see which bones would dissolve inside the human digestive system, and which bones would not. [The documented that experiment, in the study “Human Digestive Effects on a Micromammalian Skeleton,” Journal of Archaeological Science, vol. 22, November 1995, pp. 789–97.

Crandall and Stahl’s swallow-a-shrew experiment will be honored in a song that’s part of the mini-opera (the opera is called “The Plight of the Gastroenterologist”) that will premiere as part of this year’s (2025) Ig Nobel Prize ceremony.
