The cast of SBS' 'Running Man', who were whisked off to Hanoi for the episode that will be broadcast in the following weeks, shared a friendly snapshot while posing in the traditional Vietnamese attires.

Joined by their guests Lee Dong Wook and Han Hye Jin, the cast looked as friendly as ever, but the good-natured snapshot turned hilariously frightening when fans noticed Gary photobombing with his zombie-like expression that went unnoticed by the others in the front.

Viewers, who are already used to Gary's hilarious antics on the show, found his zombie look rather endearing, leaving comments like, "Gary your zombie look is daebak", "He is definitely full of charms", and "Keke, Gary oppa,�what are you doing by yourself?"
