I can think of 4 things that would horrify me to find down there
My Ex Mother In Law, Seeing her was bad enough never mind finding her living with me and rent free!!
Antony Worrel Thompson Naked, with mint leave over his Parts and a strawberry in his mouth, Wagging his finger at me and telling me I forgot to add something to my latest Strawberry Flan!!
A Vampire with my Donor Card and an empty glass winking at me!!
A Girls Aloud concert live in my basement with no escape
