A monkey is sitting in a tree smoking a joint when a lizard walks past, looks up and says to the monkey
"Hey, what're you doing?"
The monkey replies, "Smokin' a joint, come up and have some."
So the lizard climbs up and sits next to the monkey and they smoke a few joints.
After a while the lizard says his mouth is 'dry' and he's going to get a drink from the river.
The lizard is so stoned that he leans over too far 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?"
