That was some funny sh!t... I love hearing people do an Aussie accent, cracks me up! i could load you up with 100's of slang sayings from aus.
"Fair shake of the sauce bottle"
"Don't come the raw prawn with me"
"I'll slap you seven ways from sunday"
"Your not the sharpest tool in the shed"
"I'll give you somethin' to bloody cry about" (maybe that was just my old man...)
"Better than getting stabbed in the eye by a pencil"
"You can't trust anything that bleeds for a week and doesn't die"
"Your just like a mud flap, shiny on top and sh!t underneath"
Clearly this is posted in what is labeled as comedy. All is said in jest.
