The Potion that Backfired

What happens when a potion goes wrong!

The Potion That Backfired!:

"Bubble, Bubble, Toil and Trouble!" chanted the wicked old hag.

The concoction inside her cauldron began hissing and spitting.
She began to add more ingredients which included:

Some of her old rags, and handbags, as well as her "Fairest of Them All!" model mags.
All of a sudden the smell of the potion began to make her gag.
She soon collapsed to the floor with an almighty crash and that was the end of that wicked old hag!
