There are many methods of taking the human temperature and with each it's set of problems. Oral is subject to the last thing you had to eat, axillary (armpit) is subject to outside temperature, and rectal is subject to getting you beaten for trying to take it there. Unfortunately rectal is the most accurate other than Kidney, but you have to be dead to take it there. Others such as tympanic, temporal and others are proving to be much less accurate that originally thought.
