Manual System

MARY has a thingamajig clamped on her ears
And sits all day taking plugs out and sticking plugs in.
Flashes and flashes—voices and voices calling for ears to pour words in
Faces at the ends of wires asking for other faces at the ends of other wires:
All day taking plugs out and sticking plugs in,
Mary has a thingamajig clamped on her ears.
