Sense Sonnet - Pumper

 Model 500

Model 500 telephone,

I was the standard model made

By Western Electric, black tone

Was only available shade.

Ma Bell did loan my kind out to

Customers, and only phone that

The customers could use to do

Calling up another to chat.

This was the rule Ma Bell enforced

Up until 1984,

When Ma Bell had to get divorced,

Her monopoly was no more.

So what, you ask, happened to me?

In a museum I now be.
