The only creature immune to an adorable baby panda's charm is another baby panda.
So while even the sleepiest human would be all too happy to give into little Mei Huan's nudges, his brother, Mei Lun, has learned to ignore the panda pokes during naptime.
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).
