How much water did you drink!?

A  koala was sitting in a gum tree smoking a joint

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 you!'

The koala looked  down at him and said,

'Shiiiiiiiiiiit  dude...
How much water did you drink!?'
