A panda walks into a bar, goes right to the counter, grabs a sandwich and after having eaten it he takes a gun out of his pocket and shoots the bartender. Then, as though nothing had happened, he walks out. Everyone in the bar is sitting all speechless and petrified but suddenly someone breaks the silence:
-What a hell was that?!?
Comes a sorrowful voice:
-It was a panda.
-???
-Perhaps you don't know what a panda is... It's a mammal that eats, shoots, and leaves.
