Come to the edge.
We might fall.
Come to the edge.
It's too high!
COME TO THE EDGE!
And they came
And he pushed
And they flew.

Christopher Logue's poem "Come to the Edge" from New Numbers (London: Cape, 1969) pp. 65-66. It was originally written for a poster advertising an Apollinaire exhibition at the ICA in 1961 or 1962, and was titled "Apollinaire Said"; hence it is often misattributed to Apollinaire (Source: Quote…Unquote Newsletter, July 1995, p. 2).
