Sex and humor have something else in common: They are often among the first things that totalitarian regimes try to stamp out when they take power.
We're certainly not living in a totalitarian state in Australia. However, governments of all stripes do have a tendency to seek more power over people's lives than less. (And freedom of expression is certainly an issue that many people are concerned about now. The present Labor Government's plans to filter the internet have a lot of people really angry - and not just social libertarians.)
For these reasons it's not surprising that the famous comedian Sandy Gutman - aka "Austen Tayshus" - is running as a candidate for the determinedly anti-censorship Australian Sex Party.
