beyond the wide world's end

Classic example; we had a Chilean fan staying with us for a couple of weeks a decade ago, so we took her to the Museum.

She stops in the Great Court, looks at one of the exhibits and goes 'Hey! They've got a replica of an Easter Island moai!'

Us: 'er... this being the British Museum, that's probably not a replica.'

Her: 'Oh, come on! - what are the odds of them a) getting one and b) shipping it halfway across the world?'

We went and investigated.

Needless to say, it was.
