I was working on something arbitrary when I overhear this exchange:
Technician: "Yes ma'am, can I help you?"
Lady: *mumble mumble* "Willow bark."
Technician: "I'm sorry, what was that?"
Lady: *mumble mumble* "I'm looking for willow bark...."
Technician: "Umm... Ok. What is their date of birth?"
Funny thing is, you can almost be guaranteed that some child, somewhere, has the name "Willow Bark."
