The Mall's Balls

For those who are not familiar with the centre of Adelaide, the main shopping area is known as Rundle Mall, which is actually a road that is blocked off to cars with shops down both sides.

One of the landmarks in the Mall is a sculpture of two large super shiny silver balls (probably 6 feet across, each) sitting one on top of the other. They have been there since the '70s. This of course has lead to the classic Adelaide-only joke of "What is long and straight and has 2 balls?" - the punchline writes itself really.

Anyway, Callum encountered the "balls" today.
