The Tate Modern in London is displaying a new installation comprising of an enormous crack in the floor of the Turbine hall.
Completed by a Colombian artist (Those Colombians love their crack, don't they) the 'piece' is called "Shibboleth"
Shibboleth was a sacred word of the Ephraimites who used to make visitors say it in order to determine which part of the region they were from.
Any mispronunciation suggested the poor sod was an "outsider" which resulted in instant death.
The link between the word "Shibboleth" and a 532ft crack in the floor is described by leading art critics as "A fucking mystery"
Although if you have been to Tate Modern you may have noticed that almost all of the "art" on display is shit.
