Girl Can't Stop Laughing While Trying to Prank Mother

This girl was trying to prank her mother. She made a butterfly on a paper and asked her mother to identify it. Then she rolled the paper and inserted its both ends on both her mother's thumbs. After that, she asked her to repeat the word 'wing'. However, the moment her mother started saying it repeatedly, she picked up the paper acting like she was answering a phone. They both laughed hysterically on that silly act.
