A panda bear walks into a restaurant, sits down, and asks the waiter to bring him a plate of bamboo. After the panda eats all of it, he takes out a gun a kills the waiter right then and there. The restaurant owner was horrified. He says to the panda bear: "Why did you do this?", to which the panda replies: "Look it up in the encyclopedia." The restaurant owner takes out his encyclopedia, and under the entry of panda bear, he finds: "Panda. Giant mammal indigenous to China, eats bamboo and shoots."
