Chimps

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.

Chimps are highly intelligent beings. Arguably smarter than some of the humans we know. So one would think a beast with such a curious mind wouldn't be so happy about having to live in a cage at a zoo, and would be using its substantial brain power to plot an escape. And you'd be right.

Kanzi, a bonobo chimp raised in captivity has had what his handler calls a "passion" for fire ever since he watched the movie 'Quest for Fire' as a young ape. Now 31, Kanzi is able to make a controlled blaze by rounding up twigs and then igniting them with a lighter. A fire-starting chimp -- WHAT COULD POSSIBLY GO WRONG?

Cheetah, the chimp who starred in the Tarzan films of the 1930s, has died in the Suncoast Primate Sanctuary in Palm Harbor, FL of kidney failure at the age of 80. The beloved ape moved into the sanctuary in 1960 after living on the estate of Johnny Weissmuller, who had portrayed Tarzan in the films.

In an interview with Meredith Vieira on 'Today,' chimp attack victim Charla Nash showed off the new face she received after a groundbreaking 20-hour transplant operation six months ago.

In a stunning case of "monkey see, monkey do," two chimps at the St. Louis Zoo walk in such perfect, stride-for-stride unison that they look like CGI recreations of each other. This one has to be seen to be believed.

Charla Nash, the Connecticut woman who was horribly mauled by a chimp in 2009, gave her first post-operative interview to Sky News after receiving a groundbreaking face transplant.
