A man was sitting quietly reading his paper when his wife walked up behind him and whacked him on the head with a magazine.

'What was that for?' he asked.

'That was for the piece of paper in your trouser pocket with the name Laura Lou written on it,' she replied.

'Two weeks ago, when I went to the races, Laura Lou was the name of one of the horses I bet on, I bought you those flowers with the winnings,' he explained.

'Oh darling, I'm sorry,' she said. 'I should have known there was a good explanation.'

Three days later, he was watching TV when she walked up and hit him in the head again, this time with a frying pan, which knocked him out cold.

When he came to, he asked, 'What was that for?'

'Your horse phoned.'
