Or at least they do in McDonald’s commercials advertising the arrival of the McFlurry (they didn’t have it until now in Japan?):

Readers have contacted me to tell me that certain McDonald’s locations in Japan are offering free McFlurries with sets purchased after 2:00PM. The McDonald’s Japan homepage also says that anyone who goes to a McDonald’s restaurant between May 1st and May 6th and says the secret code word “Fururirero!” will get a special coupon allowing them to buy a McFlurry for 100 yen. During the same period, McFlurries will be sold at 150 yen (half price).
