"I have a can of yams that I believe has been passed down from nomadic mother to nomadic daughter in my family for three or more generations." --ToastedSuzy's Posted Musings

Here's another mention of a can of yams dating back to the 1970s, still waiting to be opened.

The yam-shaped South Pacific island of Ambrym owes its name to Captain Cook, who anchored off there in 1774.  Ambrym means “here are yams” (ham rim in Ranon language).

Some yams are works of art:

Silence of the yams

A pregnant woman's "Self Portrait as a Yam"

I yam what I yam

Beached Yam

Beware the dragon, lest he eat your yams!

A still life with a yam, and another (including plant parts and dead animals)

New Guinea yam masks

Men carrying yams

Yams in a basket

Monochrome yams

Yam leaf collage

Yams in orange

Oiled yams

Pastel yams

Colored pencil yams

Little yams art collective

A one-act play entitled The Can of Yams was penned by the inimitable Jonathan Caws-Elwitt.
