Word of the Day: Moley

I found the following in the OED:

Moley, n: A potato in which razor blades are embedded, used as a weapon.

It provided the following usage example, from the Spectator, in 1959:

I suppose if I go on criticising him I shall end up by having the boys with the moleys call on me one dark night.

Who knew?

And how exactly does a moley work? Do you throw it? Explode it? Or is it meant to be ingested?

On the other hand, I seem to remember you posting an early April Fool’s prank last year….
