If there's one thing that humans and animals agree upon, it's that medical tools can be mighty cold. In this pic, a newborn baby gorilla winces as a doctor uses a freezing stethoscope during an examination at Melbourne Zoo. If the gorilla thinks this is bad, just wait until he gets the bill.

For evidence that human and gorillas are almost genetically identical, look no further than this adorable image. In fact, we've probably made the same face ourselves.

Next time, try warming it up a little, doc. Is that too much to ask? A little courtesy and bedside manner go a long, long way. Even in the animal kingdom.
