Apparently, there is a rubber band inside it.

Did you  know that
A self-defrosting refrigerator
Just has a channel and a little hole in the wall
Behind that is a small  sponge
So much for modern technology.

Now my DVD player won’t open
Apparently, there is a rubber band inside it.
They gradually dry out
Then the machine won’t work
Do they think I will take it apart?
I’ll go the cinema and see a film there
One might have thought after Einstein and Heisenberg
And Goya, Picasso and Paul Klee
We’d have found a better way
Of dealing with the every day.
