How can you fit the element boron into a nursery rhyme?

Little miss Muffet sat on a tuffet, eating her boron and whey. The dish was quite sour, and within an hour, miss Muffet had soon passed away.

This is just an example, but you could probably fit boron into any nursery rhyme by keeping the first line intact while fitting in the Word 'boron', and then basing the second line solely off of creative imagination.
