Men At Work - Who Can It Be Now?

Who can it be knocking at my door?
Go 'way, don't come 'round here no more.
Can't you see that it's late at night?
I'm very tired, and I'm not feeling right.
All I wish is to be alone;
Stay away, don't you invade my home.
Best off if you hang outside,
Don't come in - I'll only run and hide.

Who can it be now?
Who can it be now?
Who can it be now?
Who can it be now?

Who can it be knocking at my door?
Make no sound, tip-toe across the floor.
If he hears, he'll knock all day,
I'll be trapped, and here I'll have to stay.
I've done no harm, I keep to myself;
