I found this joke on the page of one of my Facebook friends:
A guy 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.
When he came to, he asked, 'What was that for?'
'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,' 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.
'Your horse phoned.'
