A koala is sitting up a gum tree ... smoking a joint when a little lizard walks past and 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 burn a few.
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 in to 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:

"Shiiiiiiiiiiit dude . how much water did you drink?!!"
