Was once sent from a private clinic, 2 silicone bags from a prosthetic breast removal.
They were labelled "Full cities".

I presume the conversation (between 2 auxiliary nurses) went something like....
"Hey Mabel, what shall I do with these?"
"Send them to pathology"
"What shall I call them?"
"False titties".

But I'm guessing:-)
