A koala is sitting up a gum tree smoking a joint when a little lizzard 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 lizzard climbs up and sits next to the koala and they have a few joints.
After a while the little lizzard says his mouth is "dry" and is going to get a drink from the river.
But the little lizzard is so stoned and he leans too far over and falls in the river.
A crocodile sees this and swims over to the little lizzard and helps him to the side, then asks the little lizzard "What's the matter with you?"
The little lizzard 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?"
