The 3-year-old pooch named Ken-kun is always front and center when someone approaches "his" sweet potato stand in Japan. Customers reportedly open the white box and choose a sweet potato of their choice, then place the money into a small hole. There's even a wonderful little sign by the stand that reads: "Because I'm a dog, I can't give you change." As you can see, it's all based on the honor system and we want him to just take our money right now!
