For God's sake Possum, take this joke down

 The flat earthers, will start to use it as proof 

Joking apart

I was in a free camp, (a few years ago), and spotted a vehicle which had a sign, which said

I am a flat earther, on a journey to the end of the earth

Or words to that effect

I did not talk to the driver of the vehicle, to ask if he was dinkum, or just joking

I knew that I would laugh, whatever his answer was
