The Kiki Series is a series of competitions where each member tastes a randomly selected product, mostly food and drink but once cigarettes, from many different brands blindfolded. After the tasting period, they must find the product they tasted from a selection of 8 to 20 different products of various brands. Anyone who selects correctly will receive a 100,000 yen prize money, otherwise they take a variety of punishments, such as being hit in the groin by aChinko Machine or, more commonly, getting slapped or sprayed CO2 gas by a foreigner.
