Minna no Joushiki Ryoku TV (Everyone's Common Sense Power TV) has family members testing their common sense knowledge: Like, how to pick up chopsticks, using certain words or identifying things. In the commercial above, the game has family members saying each other's birthdays. So the father has to guess his wife's, which he has totally forgotten. Odd, because I thought it was common sense not to play games that involve recalling things like your wife's birthday, your first date and when your anniversary is.
