When I was a boy, I owned a small plastic skull, a trinket from some store or vending machine. It came with those tiny, automatic puffing cigarettes associated with Adams brand "Smokie Pets" of the same dime-store era.
One of my parents would light it up and I would watch, transfixed, as the skull blew smoke rings.
It came with six cigarettes.
When they were gone, that was that.
