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
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:

"Shiiiiiiiiiiit dude ... How much water did you drink

thats good, lol

That was good.

Y'know? I've actually DONE that, man
