The Kuala and the Lizard

So this Koala is sitting in a tree smoking a spliff. Small lizard walks by and ask the Koala what he's doing. Koala says "Having a spliff man, come up and have a few puffs..."

So up the lizard goes, but after a few drags he's thirsty. Koala says "No problem little dude, just little bit down the road there's a river, go have a drink."

So off the lizard goes, but when he gets to the river he is so stoned he falls into the river onto the crocodiles nose. Crocodile squints at the lizard, says " Hey man, what's up with you, why you falling all over the place?"
Lizard says "Man you won't believe this but there's a Koala in the tree smoking a spliff, I had a few drags now I'm stoned.

Crocodile, thinks, heck I've got to go see this. So he puts the lizard down and goes to look for the Koala. Doesn't take long he finds him. So he shouts to the Koala, " Hey Koala, what you doing up there...?"

Koala looks down at him and frowns and says " Sjees dude, how much water did you drink...?!
