A frustrated wife buys a pair of crotchless panties in an attempt to spice up her dead sex-life. She puts them on, together with a short skirt and sits on the sofa opposite her husband. At strategic moments, she uncrosses her legs ... enough times that her husband finally asks,
"Are you wearing crotchless panties?"
"Y-e-s," she answers with a seductive smile.
"Thank God - I thought you were sitting on the cat."
He never heard the gunshot.
