Rikkitic:
Eating the banana was a brilliant piece of performance art, which should have considerably increased the value of the work.
Oh yes!
And it is a living artistic process, where the banana will metamorphose into its new form, post digestion, soon to be greeted with rapturous applause in a unique live performative unveiling.
It is metaphor for something, up to the appreciative art world to decide exactly what this is.
