unwelcome guest blues

I have an unwelcome guest
In my own house
And that unwelcome guest
Is not a mouse
And that unwelcome guest
Is not the cat
And my unwelcome guest
Is worse than that
And my unwelcome guest
Is not the sound
Of too many people
Sitting around
And the unwelcome guest
Is not my uncle
Even tho he may have
That dangerous carbuncle
And my unwelcome guest
You’ll know it’s true
Isn’t the reader known
As you
The unwelcome guest
I think you’ll see
Is somebody who goes
By the name of me!
