A Great One From Grumpy Down Under

A koala was sitting in a gum tree smoking a joint (as they do!)

 When a little lizard walked past, looked up and said, 
'Hey Koala! What are you doing?'

 The koala said, 'Smoking a joint, come up and have some.'

 So the little lizard climbed up and sat next to the koala 
where they enjoyed a few joints. After a while the little 
lizard said that his mouth was 'dry' and that he was going 
to get a drink from the river.

 The little lizard was so stoned that he leaned over 
too far and fell into the river.
A crocodile saw this and swam over to the little 
lizard and helped him to the side. Then he asked 
the little lizard, 'What's the matter with you?'

The little lizard explained to the crocodile that he 
had been sitting with the koala in the tree, smoking 
a joint, but got too stoned and fell into the river 
while taking a drink..

The crocodile said that he had to check this out and 
walked into the rain forest, found the tree where the 
koala was sitting finishing a joint. 
The crocodile looked up and said,

 'Hey Koala!'

So the koala looked down at him and said,

'F*** me....
How much water did you drink!?'

Thanks Grumpy and Dan!
