During their stop in Osaka, the crew spent time at a deer park, feeding the deer. When Sunggyu began worrying about the deer biting his hand, Jung Hyung Don replied, "I'll get bitten for you." 

Jung Hyung Don showed confidence as he fed senbei crackers to the deer that came trotting toward them, which encouraged Sunggyu. When the two saw the adult deer stealing the young deer's senbei, Sunggyu said, "It's a greedy hog. It's Jung Hyung Don!"

But when the two moved on to a bench to feed the deer more comfortably, one overly enthusiastic deer sent a flying hoof kick Jung Hyung Don's way, sending Sunggyu running off in fear.
