In one of Terry Prachett's Discworld books he describes the final test for Novices to become fully fledged 'Monks of Cool". They are taken into a place with all possible types of clothing and to say which is the coolest. The correct answer is "Whatever I choose to wear".

Mind you, I refuse to sing "swallowed a peanut" and one or two other songs - but generally it is because for me they are linked with some unpleasant memory.
