Mary has a thingamajig clamped on her ears
And sits all day taking plugs out and sticking plugs in.
Flashes and flashes--voies and voices
calling for ears to put 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.
