Found this rock at a popular south coast surf spot, I think we can all agree it is clear evidence of an ancient civilisation of Neolithic surf gods. Upon discovery of this ancient wonder I thought it best to offer a small libation by way of sacrificing a few sponge bobs in order to appease the all powerful surf gods and hopefully encourage them to send some nice clean swells etc. So if your reading and you want good surf, you know what to do.

Blessed is thy cutback, lead us not unto spongitude, amen
