Stretch

It's something that is not quite true
And fits some limousines.
It helps before you exercise
Or lets you put on jeans.

You do it when you're waking up
Or else when tired, maybe;
And it can leave some tummy marks
When you have had a baby.

When reaching for an item
Way too high upon a shelf,
You might employ one if you want
To get the thing yourself.

If we could never use this
We'd have cause to moan or kvetch,
But we're lucky that in all its forms
It's possible to stretch.
