You know, I actually missed this episode when it first aired. These episodes were being uploaded at the same time as A2K as my free time is limited (work, kids, etc.) So I chose the new A2K episode and by the time I had free time again, another episode (of Nizi project season 2) was up, so I decided to watch that instead. Edit: in the 3-legged race, they are saying "1, 2, 1, 2, 1, 2"
We have similar games in the USA like the 3-legged race or pin the tail on the donkey. You've never played these types of games at a family BBQ (or something similar)?
