The phartus minimus has a minimal atmospheric effect and a very low OOU, or Offensive Olfactory Unit, count (see Figure 1). If your hearing is poor, this particular variety may pass unnoticed.
Phartus minimus is usually produced in abundance by children, gynecologists, parakeets, large insects, small rodents, chihuahuas, Afghan hounds, cats of all types (Assuming they have not used up their nine fart embryos. See phartus felinus, page 33.), scientists, hairdressers, ballerinas, male strippers, Sunday school teachers, accountants, clerks, ministers, florists, and little old ladies. They are most prevalent in churches, elevators, and aboard common carriers.
Phartus phartus is the average or ordinary, everyday variety. It is higher in volume than the phartus minimus, usually longer in duration, and produces a higher level of OOU’s. It is easily identified by sound at close range and is mildly offensive.
