Meanwhile, we have probably seen the last of the lads from ABC television's The Chaser.

What happens when the drive to be funnier and funnier turns ugly?

Do we leave ourselves open to predator humour?

By predator humour I mean jokes so low that they create a victim.

With The Chaser, whose humour we lapped up voraciously during their first two seasons, the moment-too-far was a joke at the expense of dying children.

With Jackie O and Kyle Sandilands the moment came with a truth experiment that took them to the taboo subject of rape.

How far will they go? Are they genuinely remorseful? These are all good reasons for people to switch their radio back to Kyle and Jackie

Television's Little Britain went far with its humour -- from breastfeeding adults to the beautifully tragic `only gay in the village'.

Little Britain's genius appeared to be the right blend of shock without creating predator and victim.

The Chaser became predictable and we recognised a formula. Once we're in on the joke it's not funny. When a joke is predictable and hurtful do you switch off or do you wait for more?

Last week television's Dancing with the Stars ratings rocketed after a spat between judges.

The spat invigorated interest in the rapidly declining viewer interest.

Kyle Sandilands and Jackie O obviously didn't go far enough to offend.

Are you worried about how far they will have to go?
