10 times quiz
A game where someone is asked to say a word 10 times (usually piza "pizza"), and then asked a question (usually "What is this?" while pointing to the questioner's elbow). The idea is that repeating the first word should cause the person to say another word that sounds similar (hiza "knee") instead of the correct word (hiji "elbow").
Also called 10 times game (10回ゲーム).
