Sitting In a Tree

I don't normally post jokes, but since my friend Alejandro begged me to and the joke is pretty amusing, I decided to make an exception. Should I start a joke of the week segment?

A monkey is sitting in a tree smoking a joint when a lizard walks past and looks up and says to the monkey, "Hey! What are you doing?" The monkey says, "Smoking a joint, come up and have some." So the lizard climbs up and sits next to the monkey and they have a few tokes together. After a while the lizard says his mouth is dry and that he's going to get a drink from the river. The lizard climbs down the tree, ditty bops on thru the jungle to the river and leans over to get his drink. The lizard is so stoned that he leans too far over and falls into the river. A crocodile sees this and swims over to the lizard and helps him to the side, then asks the lizard, "What's the matter with you?" The lizard explains to the crocodile that he was sitting in a tree smoking a joint with the monkey and got too stoned and then fell into the river while taking a drink. The crocodile says he's gotta check this hippie monkey out and walks off into the jungle where he finds the tree where the monkey is still sitting and toking on the joint. He looks up and says "hey you!" The Monkey looks down and says, "shit man, how much water did you drink?!!
