The worst job I ever had was in the Army, during/after the invasion of Grenada. I got stuck with a couple of other guys on corpse cleanup duty which was pretty horrible once the corpses had sat in the fields or the jungles rotting for a few days. That's how we found a fair number of corpses, just from the smell. We had to use humor to deal with that job, grisly morgue-type humor. If we couldn't have laughed, we'd surely have cried. No extra pay for cleaning up the corpses either (although there was a little extra just for being in a combat zone).
