One of the week's viral photos got that way for a nice reason. The image shows a giraffe at the Blijdorp Zoo in Rotterdam, Netherlands, giving a kiss of sorts to a terminally ill zoo worker, reports ABC News. Mario Eijs, who is mentally disabled, has a brain tumor and asked to pay a last visit to the zoo where he had worked as a cleaner for 25 years. A curious giraffe approached the 54-year-old and nuzzled right in. A group called the Ambulance Wish Foundation arranged the visit, reports AP. "Mario got a lick on his nose after a lot of snuffles," says a foundation worker.
