The Ultimate Competing PhD Dissertations:

What ARE little girls and boys made of?

Those with competing affections for girls and boys would battle to a well-researched conclusion. (Personally, I think we girl lovers would clearly have this one in the bag.)

"What are little boys made of?

Snips and snails, and puppy dog tails;

And that’s what little boys are made of.

What are little girls made of?

Sugar and spice and everything nice;

And that’s what little girls are made of."

(At least before the public schooling system gets hold of them.)
