Here’s a perfect example of the good kind of troll — the one who leaves no high five left behind. Everyone wants a special snapshot when they visit a historical monument like the Leaning Tower of Pisa, and Darius Groza wants to make sure visitors get that perfect image.

The prankster, who writes for Romanian blog JEG, runs into pictures and gives a big high five to tourists posing ironically like they’re holding up the building.

What’s not ironic is the fact that a Radiohead cover of “Creep” is playing in the background. Who wants to see more good-hearted pranks like this on the Internet? Sound off in the comments.

At Seattle Children’s Hospital, one floor is full of kids fighting battles that no one should ever have to face — especially not at their age. For a moment, however, the ward was filled with hope and joy from the most unlikely of sources.

In the above video, the ward’s patients and staff lip-dub to Kelly Clarkson’s song “Stronger.” The video below shows footage from behind the scenes.

The Hematology-oncology ward covers the diagnosis, treatment and prevention of blood diseases and cancer.

We understand if you have “something in your eye” by the end of the clip.

Ever eat something that doesn’t taste as good as it looks? Luckily, a lioness named Kya at the Oregon Zoo didn’t have a chance to find out how this little boy tasted.

The lioness was going after a zebra — which was actually a one-year-old named Jack, who was wearing a black and white striped sweatshirt. Jack, thankfully, was behind a thick glass wall, so no injuries occurred.

The unforgettable moment, which happened on April 26, was captured on video and uploaded to YouTube. The video has since gone viral, with more than 155,000 views.

“It was Jack’s first trip to the zoo,” Jack’s mother Heather Baltzor told the Huffington Post. “We didn’t even realize he looked like a zebra until we got home but a lot of the animals in the zoo — the crocodiles and the jaguars — apparently did. They would come up to the glass and look at him.”

The video above tells the story of a blind, homeless dog that has been given a second chance, thanks to the friendship of another stray puppy.

Tanner, a 2-year-old Golden Retriever, was born blind with a slight seizure problem. After his owner died, the dog was forced into a shelter.

The stress of the loss led to a increase in the severity of his seizure disorder, and he became panicky. His future seemed to be bleak.

That was untill Tanner met Blair, a 1-year-old black Labrador mix who had been living on the streets before he was brought to the animal hospital after being shot, according to The Daily Mail.
