A koala is sitting up a gum tree smoking a joint when a little lizard walks past ,
looks up and says "Hey Koala ! what are you doing?"
The koala says: "Smoking a joint, come up and have some."
So the little lizard climbs up and sits next to the koala and they have a few joints.
After a while the little lizard says his mouth is 'dry' and is going to get a drink from the river.
But the little lizard is so stoned that he leans too far over and falls into the river.
A crocodile sees this and swims over to the little lizard and helps him to the side, then asks the little lizard: "What's the matter with you?"
The little lizard explains to the crocodile that he was sitting smoking a joint with the koala in the tree, got too stoned and then fell into the river while taking a drink.
The crocodile says he has to check this out and walks into the rain forest, finds the tree where the koala is sitting finishing a joint, and he looks up and says "Hey you!"
So the koala looks down at him and says:
"Fuuuu - k dude.......how much water did you drink?!!"
