Who Me
Who, Me? was a top secret, sulfurous, non-lethal chemical weapon developed by Massachusetts [Institute of Technology|MIT]-graduate Ernest Crocker while working in the Research and Development Branch of the Office of Strategic Services during World War II, to be used by the French Resistance against German officers. Who, Me? smelled strongly of fecal matter, and was issued in pocket atomizers intended to be unobtrusively sprayed on a German officer, humiliating him and, by extension, demoralizing the occupying German forces.
The experiment was very short-lived, however. Who, Me? had a high concentration of extremely volatile sulfur compounds that were very difficult to control: more often than not, the person who did the spraying also ended up smelling as bad as the one targeted. After only two weeks, it was concluded that Who, Me? was a failure.
