Collecting semen for artificial insemination has got to be one of the most disgusting jobs in the world. Someone has to climb into a wooden structure saturated with pheromones to incite the bull/stallion into a breeding mood, and when the structure is mounted, said operator has to literally collect the semen inside of a sterile cup when the animal ejaculates. That was on one of my top 10 lists for "I'll never describe my job to anyone," lists.
