Bet you’ve never seen the queue for Sydney Opera House look like this!

5000 nekkid botties and their owners volunteered to be part of artist Spencer Tunick’s ‘Nude Art Installation’. The queue began at the Opera House forecourt stretching right round to the Museum of Contemporary Art, even spilling on to the Royal Botanic Gardens.

The official name of Tunick’s installation is The Base – with all bottoms shaped like a giant upside-down triangle.

Now…no wise-cracks, please!
