My mother used to sing:

'Neath the crust of the old apple pie
There is something for you and for I.
It may be a pin that the cook just dropped in
Or it may be a dear little fly.
It may be an old rusty nail
Or the tip of a pussy cat's tail,
But whatever it be, it's for you and for me,
'Neath the crust of the old apple pie.
