The world is an amazing place where almost anything can happen. For instance, you may have never thought about conversing with pigs. Nor has Air Mail Pilot ever thought about conversing with pigs. But someone has: a professor at the University of Copenhagen. She not only thought about conversing with pigs, but then went and did something about it, compiling what The Times of London calls an “oink-tionary,” which “translates pig grunts into the emotions they represent.”

Elodie Mandel-Briefer is a biologist whose main field of research, according to her Web site, is “animal bioacoustics and behavioral biology, vocal expression and contagion of emotions in ungulates.” In other words, she studies how hoofed mammals like pigs, horses, camels, and sheep communicate with one another. “Pigs are very vocal,” she explained to The Times. They’re also famously smart and known to express emotion through sound, and thus made excellent subjects.
