Russian Scientist Stitches the Head of a Puppy onto a Larger Dog

From The Wikipedia Article:
"Vladimir Demikhov (1915 - 1998) was a Soviet scientist who did several transplantations in the 1930s and 1950's, such as the transplantation of a heart into an animal and a lung-heart replacement in an animal. He is also well-known for his transplantation of the heads of dogs. He conducted his dog head transplants during the 1950s, and this ultimately led to the head transplants in monkeys by Dr. Robert White, who was inspired by Demikhov's work. This inspired the aliens in Tim Burton's movie Mars Attacks! to transplant the head of Sarah Jessica Parker onto a dog and vice-versa."
