Nothing compares to the joy of having a sister.

You can't live with them, yet can't live without them. There's something quite special about having someone who's like you but not entirely the same. Your sister helps along the path of life when you're giggling at your old-fashioned parents, trying to get out of chores or even the most basic essentials, like trying to buy a sneaky naggin. One pair of sisters in America have gone viral for their high jinks and we can't stop giggling. Emily Petrozza, spent a weekend in the outdoors, exploring with friends and fishing but when she arrived home, she noticed she had a rash on her arm and bump around her eyes. She showed her injuries to her sister Lauren who took a photo, thinking nothing of it and went to bed. The next morning however, Emily awoke crying from her bed with pain as her eyes had swollen over her eye sockets which only made her sister Lauren DIE laughing. Seriously? She looks scary as hell! After Lauren tweeted the pictures of her suffering sister out, Twitter users were quick to compare poor Emily to characters from movies!

Following medication and a few days rest, the swelling slowly went down.
