Hunkalicious zookeeper Grant Kother, of the London Zoo, bared all to help raise awareness for an upcoming naked run which raises money to save the dwindling number of Sumartran tigers. The “Streak for Tigers” run will take place on August 15th and has set a goal of at least having 300 runners to represent the 300 remaining tigers in the wild.

“We’re thrilled to be holding such a daring and unusual event after hours at ZSL London Zoo,” Events manager Lucy Osman explained. “We’re hoping that by taking on this outrageous challenge, streakers’ friends and families will dig deep to show their support and help protect tigers around the world.”
