A bit vulgar but I heard this on a podcast last night and couldn't stop giggling:
A lion sees a spring while running through the jungle. He leans in to take a drink, head down, rear up and his tail swaying in the air. A gorilla wanders by and gives the lion the old Liberace and runs off. The lion gives chase through the jungle. The gorilla comes upon a campsite at the edge of the jungle and dashes into a tent. He grabs a hat, puts it on and picks up the New York Times. The lion runs by and pokes his head in the tent and asks "Did you see a gorilla run by here?" The gorilla says, "you mean the one that fucked that lion in the ass?" The lion says, "it already made the paper?!"
