Black Fella’s The Booze Bus...!!

Two indigenous Australians were driving their old
Ford Falcon in the outback recently, when off in the distance they saw a police "booze bus".
Rather than trying to avoid it, the driver headed straight for it. As they pulled up, the driver wound his window down and said 'G'day, brudder! Two cans of Emu Export, thanks!'
The copper glared at him and said 'You must be drunk!
Get out of the car and blow into this tube!'
The driver said 'Sorry boss, I can't blow in that, I got a letter from the doctor saying I'm asthmatic and I'll pass out if I blow in that.'
The cop smirked and said 'OK - in that case, we require you to give a blood sample.'
'Nah, nah - sorry, boss,' replied the driver. 'Can't be doin' that. Got a letter from the Red Cross sayin' I'm a haemophiliac, and I could bleed to death if I gavea blood sample. Sorry, boss, can't do that!'

By now the copper was getting very irate, and so he demanded that the driver provide a urine sample for testing.
The driver shook his head and said 'Sorry boss, can't do that either.'
The copper protested 'Surely you haven't got a letter for that!!!'
'Bloody oath, mate!' says the driver, 'It's from Julia Gillard, the Prime Minister of this lovely country of Australia - she's apologised, and says you white fellas can't take the piss out of us black fellas no more!
