Its worth noting that the Turkey Slap wasn't why they finished Adults Only, It had already wrapped several weeks before hand, The ACMA's result into their investigation into the 2005 Uncut season (The dick on the shoulder scene and sexual scat fetishes discussion in particular) coming out around that time.
Although it didn't find any breach to the code itself, and Ten implemented some tweaks to how they approached Uncut/Adults Only, they still decided to cut it early anyway because of the political and community pressure that lingered. THEN the Turkey slap happened and ripped that public discussion wide open again even though it was never shown on TV in any shape or form.
