What Are Little Boys Made Of?

Remember the nursery rhyme?  Something like:

Sugar and spice and everything nice,
That's what little girls are made of.
Frogs and snails and puppy dog tails,
That's what little boys are made of.

Don't forget worms.

And this would be the part where I am backing away furiously while Daddy encourages Jack to "give the worm to Mommy".

Boys.

I'm screwed.
