If I remember right it goes something like this:
What are little boys made of?
Snips and snails, and puppy-dogs' tails,
That's what little boys are made of.
What are little girls made of?
Sugar and spice, and everything nice,
That's what little girls are made of.
So that makes me say Snips and snails, and puppy-dogs' tails, or if you go with the food answer, chocolate chip cookies and ice cream from last night.
