Paramedic Joke

A girl went grocery shopping; she loads the food in her car's back seat. She gets in, hears a loud "pop!", and feels the back of her head get hit. She feels back there, checks her hand, and sees "ooze". She knows she's been shot in the head. She calls 911 and tells the emergency operator she's been shot in the head and will hold her brains in her skull, waiting for the ambulance. Paramedics arrive, and tell her she was indeed shot ... by her can of biscuit mix.
