FedEx Blues lyrics

Basically, what happened was I was
Waiting for a package, but the
Package never came and then they
Sent me an email

And the email said, "Congratulations! We've
Delivered your package", but I
Thought, "No, you haven't, no one's
Rung on the doorbell"

So I read the email again and they
Had my address right, and they
Said that it'd been signed for by a
Name I've never seen in my life

So one of two things has happened: they've either
Delivered it to the wrong address, or there's
An invisible man in my house signing for
Packages on my behalf
