A koala is sitting up in a gum tree, smoking a joint, when the little iquana 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 iguana climbs up and sits next to the koala, and they have a few joints. After a while the iguana says "My mouth is dry. I'm going to get a drink from the river." But the iguana is so stoned that he leans too far over and falls in the river. A crocodile sees this and swims over to the iguana and helps him to the side, then asks him "What's the matter with you?" The iguana explains to the crocodile that he was sitting in the gum tree with the koala smoking a joint, 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 forest, finds the gum tree where the koala is sitting, still finishing a joint. He looks up and says to the koala, "Hey, you!!" So the koala looks down at the crocodile and says: "Dude . . . . . . how much water did you drink?!?"
