A little know scientific methodology which is very powerful and often used by many well known scientists is called "digitus in aurem". The way it would work is, you take your "digit" which is your finger, and then you carefully insert it in your "aurem" which is commonly known as ears, and do it on both sides and while you have secured your aurems tightly you make the noise nanananana until your opponent gives up and walks away, at which point you have officially proven your theory.
