You Bet You Are... The Many Voices In Abbott's Head

"I'm going to shirtfront Mr Putin, you bet you are - I bet I am."
The most intriguing thing for me about this recent bit of idiocy from our PM is the 'you bet you are' bit. What on Earth is that all about? What is actually going on in this guy's head? Was this another voice in his head backing him up? Does he have multiple personalities in his head in constant discussion with each other and this bit of dialog accidentally slipped out?
Maybe the full, uncensored quote could have gone a little like this: "I'm going to shirtfront Mr Putin, you bet you are. Ooh by crikey you are sooo going to shirt-front that bear-cuddling fag, and Tone, my man, when you shirtfront someone they know they've been shirtfronted. You bet they do. You know they do, don't I... erm who's speaking now? Me, I am, and I don't want a pansy shirt-fronting, I want to bend Putin over and poke him from behind like that cellar scene with the gimp in Pulp Fiction, man that was a hot scene, I really liked that scene... didn't we? You bet we all did." 
Or something like that.
