Oh dear. Well, my sister's didn't start out with a mess, but sure ended up that way.

Molly (long-haired tuxie) liked to sleep on top of the kitchen cabinets.
My sister was having a gentleman friend over for dinner. He liked to cook so they stayed in and putzed around the kitchen together.
He opened the fridge, bent over and stuck his head in the fridge looking for some ingredient.
Molly decided now was a good time to jump down from her perch -- and landed on his back.
He reared up, smacking his head on the glass shelf in the fridge. Food went flying all over the kitchen.
He was knocked out cold. Head wound from the shelf. And you know how head wounds bleed.
He came to. Cleaned him up and took him to the emergency room for stitches. Dinner was never finished. Never had a second date. Molly was unconcerned about the havoc she had created.
