I think it was her mental health
Well, to begin with anyway
She was always slightly weird in a weird sort of way
One day she decided she was a witch
Great big pointy hat and broom
Casting spells in all directions
Made big Joe infertile
Kept pointing to his groin, infertile, infertile
Then she got even weirder
Decided she was pregnant
Kept it up for months
Even the bump got bigger
Though the weird thing was
A baby appeared
It was decided this baby wasn’t by magic
People looked at big Joe in a different light now
In a weird way
Like maybe, he wasn’t infertile after all, and
She wasn’t casting spells
She was casting aspersions.
