Leonard loves magnesium and that's just what he eats,
But, when Leonard eats magnesium he soils his good sheets,
Leonard goes to the laundromat to wash away his soils,
But, then everyone else after him are left with Lenny's spoils,
Now, what if Leonard someday chooses to get married?
Well, perhaps Leonard's diet may have to be more varied,
And, in case anyone thinks that my story is too cruel,
Just remember that dear Leonard might be swimming in your pool.
