One of the worst old stoner jokes

so why am I laughing?

The Monkey and The Lizard

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 hits.

After a while the lizard says his mouth is dry and is going to get a drink from the river. 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 smoking a joint with the monkey in the tree, got so stoned he fell into the riverwhile taking a drink.

The crocodile says he has to check this out and walks into the jungle, finds the tree were the monkey is sitting, finishing the joint. He looks up and says, "hey!"

The Monkey looks down and says, "man, just how damn much water did you drink?"
