7-year old Sean was visiting a zoo in Ireland with his family. The hungry tiger decided it was lunchtime and didn't notice the glass barrier. He lunged at Sean, much to the amusement of Rob, his father. The New York Post quotes the father:
Fortunately, Sean “reacted pretty calm,” Rob told Storyful. However, the dad adds that his other son “ran like the clappers” — UK slang for “very fast.”
