Putrescine and cadaverine actually smell just like... Semen. Gross, overwhelming splooge. But not particularly incapacitating or vomit-inducing, looks like Neal didn't do his research. Bradford pears also smell similar, though tending a bit more fishy. (Grad school, a project next door involved making a whole library of polyamine derived chemical probes, so we got basically all the flavor notes of semen in succession. The lols outweighed the unpleasantness.)
