Pick A Sample

I have a routine checkup scheduled with my doctor in a few weeks so I went today to have the normal lab tests performed prior to my appointment.
    As the lab technician told me she wanted a urine sample she reached into this Halloween bowl for an empty, sterile sample container.
I guess there's no reason not to bring the witches, ghosts, and zombies into the whole laboratory experience.   It might even bring a smile to a nervous guy getting some of his blood sucked into a tube.
