Hi Steve and welcome to the forums from another Aussie (kind of) - I'm a Kiwi at heart.
Nice bike. My son has one just like it.
Here's one I thought you might enjoy.
A policeman in Sydney pulled over a driver who'd been weaving in and out of the traffic.
He approached the car window and said, "Sir, I need you to blow into this breathalyser ."
The man reached into his pocket and produced a doctor's note. on it was written: "This man suffers from chronic asthma. Do not make him perform any action that may leave him short of breath."
The officer said, "OK then; I need you to come and give a blood sample."
The man produced another letter. This one read: "This man is a haemophiliac. Please do not cause him to bleed in any way."
So the police officer said, "Right, I need a urine sample then."
The man produced a third letter from his pocket. It read, "This man plays Cricket for the English Cricket Team. Please don't take the piss out of him."
