Include Me Out

I grabbed the new Who's Who to see
My name; but it was not.
Said I: "The form they posted me
I filled and sent; so what?"

I searched the essies," dour with doubt . . .
Darn! It was plain as day
The scurvy knaves had left me out . . .
Oh was I mad? I'll say.

Then all at once I sensed the clue;
'Twas simple, you'll allow . . .
The book I held was Who WAS Who -
Oh was I glad; and how!
