STUDY ADVISES CATCHING HEAT STROKE FROM BEHIND: What’s the best way to check someone for heat stroke? Not to sound rude, but stick it where the sun don’t shine:

REUTERS HEALTH reports that according to a latest study, rectal thermometers are the most accurate in reading the temperature of the human body. Correct readings can help prevent heat exhaustion and heat stroke in athletes.

Researchers from the University of Connecticut tested a group of men and women by taking their temperatures after physical exertion. They found that going backdoor yielded better results than checking temps via the armpit, mouth, ear, or forehead.

Of course, the last three testing grounds can also be just as accurate as the rectal route - provided you have your head up your ass.
