Adorable Kids Try to Read Supercalifragilisticexpialidocious [VIDEO]

Supercalifragilisticexpialidocious, wrote Mathieu Cuvelier and Lucy Crook.

The word -- popularized by the 1964 Disney flick Mary Poppins -- initially stumps the ABOUTAsia Schools students. But as the above clip from marketing agency The Viral Factory shows, the children eventually learn how to say the challenging word.
