a panda walks in to a cafe

he sits down, orders a peanut butter and jam sandwich and eats it...
upon finishing his lunch he stands up and takes out an uzi and begins shooting up the place and then promptly flees the scene...
one of the patrons then asks the barista "what was that all about?"
the barista then pulls out a dictionary and points to the definition of panda
1. noun, a large bear like animal that eats shoots and leaves...
