Smile and Nod
From the Super Mario Wiki, the Mario encyclopedia
The player will be on a game show in the form of their Mii and will be asked a random question. If the answer is true, the player has to nod their head, but if it's false, they shouldn't do anything. Some examples of questions are "Is <player's name> male?"; "Is it 5pm?"; "In 6 years, will it be 2012?" and "are you using <name of the form>?"
