CINEMANIA: Guess the movie title

A panda bear walks into a restaurant and orders a meal. After eating he pulls out a gun, shoots the place to the ground, and runs away. Quickly the bartender runs after him yelling, "HEY YOU CAN'T DO THIS!!!" The panda turns around and yells "Yes I can. Look me up in the encyclopedia!" So, the bartender looks up "Panda" in the encyclopedia, and it reads "Panda: increasingly rare species of bear that can be found in the eastern part of Asia. It eats shoots and leaves.”
