Art Heber, an agriculture and biological engineering professor at the university, has been employing students to smell animal excrement.
From the article:
The students' work provides Heber with data for his ongoing research on ways to improve methods for estimating a given livestock farming operation's odor emissions.... Using an olfactometer they place their noses inside, they sniff diluted samples of air that are taken from different locations on farms and diluted to represent the odors that air would have at various distances from the barn.The students earn $30 per session, which isn't bad for running around sniffing. But what career does this translate into? Political journalist?
