The only creature immune to an adorable baby panda's charm is another baby panda.

The panda cubs are almost four months old and live in Georgia at the Zoo Atlanta. You can watch all of the adorably fuzzy duo's nap sessions on the zoo's Panda Cam (warning: once discovered, this will liquidate endless hours of your time).
