A monkey is sitting in a tree smoking a joint when a lizard walks past, looks up, and says, "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. cough cough Ear.
They have a few joints.
After a while, the lizard says his mouth is "dry" and decided to go get a drink from the river.
The lizard is so stoned he leans too far over and falls into the river.
An alligator swims over to the lizard and helps him to the side, then asks, "What's the matter with you?"
The lizard explains that he was smoking a joint with a monkey in the tree, got stoned, and fell into the river while getting a drink of water.
The crocodile says he has to check this out and walks into the jungle, finds the tree where the monkey is finishing another joint, looks up and says,
"Hey, you!"
The Monkey looks down and says, "SSSShhhhiiiitttt dude. . . How much water did you drink?"
