Riddle 62

I know a boy; his name ’s my last.
And yet he is my first,
Because of all the scamps I know,
He really is the worst.

I saw him tumble down to-day
And on the pavement roll;
I saw him fight another boy,
I saw him get my whole.

His old cap was my whole, I think;
A tattered coat he had,
And yet, withal, he seemed to be
A very merry lad.
