"Bomb", "tag", "hit", "throw up", "go over", "slash", "slam"...many of the verbs in graffiti terminology describe something a graffiti artist does to a wall. But what if the words written on a wall were the wall itself speaking?
In this same interlude it doth befall
That I, one Snout by name, present a wall;
And such a wall, as I would have you think,
That had in it a crannied hole or chink,
Through which the lovers, Pyramus and Thisby,
Did whisper often very secretly.
This loam, this rough-cast and this stone doth show
That I am that same wall; the truth is so:
And this the cranny is, right and sinister,
Through which the fearful lovers are to whisper.
