POTTED LIZARD
A koala is sitting up a gum tree smoking a joint when a little lizard walks past and looks up and says, "Hey you! 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'* 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. Just How much water did you swallow?"

Good one. Gave me a good laugh to start my morning, thanks!!

That'* good!
