Well Maminerr...I'm Glad you asked.
There are 3 reasons why the wild and elusive Anglo may be addicted to his Cheese Toasties.
Theory 1
As a young boy in the mountains of Tibet our brave young warrior used to spend his days toiling over his donkey, climbing endlessly throughout the himalayas in search of wild goats to shag. After a long days "hunting" our brave warrior child would begin his return to his mothers sheeps bladder tent.
Pushing his way thru the snow, the wind tearing at his skin he would detect a scent in the air of home cooking and increase his speed, throwing himself at nature until collapsing just inside the tent where his mother would have a home cooked meal ready and waiting for him. His mother delighted in cooking and was truly excellent at it. Some years later whilst Anglo was out Goat fucking, sadly an avalanche tore down the mountainside and buried his mother.
A group of passing Buddhist monks carried him into India with them, where he spent the next 3 years of his life in the slums knife fighting for food and raping the occasional dog. He was stalking a cockroach one day and noticed Telstra was hiring and so he applied, got the job and moved thru the ranks by being as unhelpfull as possible until a position opened up in Australia and he relocated here....but he never forgot his mums cooking and as a cheese toastie is the pinnacle of his cooking talent (having lived in the mountains and on the streets of Delhi) that is all he can make..if you listen carefully you will hear a cry of "MMOOOOOTTTHHHEEERRRRRR" after he finsihes making one. He leaves his toasties lying around as a tribute or a token of his love for his mother.
The second Theroy is that he leaves them lying around in order to trap and mate with the elusive Yobbo. The wild Yobbo is a known pest in Australia and South East Africa, the wild yobbo is extremely hostile towards those who twespass on his tewatorry...here a group wild Yobbo's can be seen drinking from their prefferred "watering hole". You'll note the one holding a cigareete is clearly on heat and trying to attract a female, similiarly Anglo is turning the hunter into the hunted and trying to attract a Yobbo.

The Third theory of course is that he masturbates and must hide his cheese somewhere...DO NOT EAT HIS CHEESE TOASTIES!
Hope that helps,
