Horses!

Jonathan's reading the sports section of his Straits Times when his wife Melissa walks up behind him
and smacks him on the back of the head with a frying pan.

"Jeez Honey, What was that for?" he asks.

Melissa says, "I found a piece of paper in your pocket with 'Jessica Joy' written on it."

Jonathan replies, "Oh Dear, 'Jessica Joy' was the name of the horse I bet on at the Singapore Racecourse."

She shrugs and walks away.

Three days later he's reading his paper again when she walks up behind him and smacks him on the back of the head again with the frying pan.

He asks, "What was that for?"

She answers, "Your horse called."
