Initially, Blackbeard's head was stuck on a pole by the mouth of a river in Williamsburg, Virginia, as a brutal warning to anybody else harboring aspirations of piracy. Eventually, when the flesh had rotted away, somebody decided to do something else with it: to drink liquids out of it. Yew.
The Raleigh Tavern appropriated Blackbeard's skull, plated it with silver, and converted it into the bottom of a huge novelty punch bowl, bizarrely known as "The Infant." For over a century, the Infant remained there, occasionally being lent out to dinner parties, believe it or not.
By the 1920s, the skull had disappeared. It resurfaced sometime in the 1990s and is now on display at the Peabody Essex Museum.
