Four married guys

Four married guys go golfing. During the 4th hole the following conversation took place:

First Guy:
'You have no idea what I had to do to be able to come out golfing this weekend.. I had to promise my wife that I will paint every room in the house next weekend.'

Second Guy:
'That's nothing; I had to promise my wife that I will build her a new deck for the pool.'

Third Guy:
'Man, you both have it easy! I had to promise my wife that I will remodel the kitchen for her.'

They continue to play the hole when they realized that the fourth guy has Not said a word.

So they ask him, 'You haven't said anything about what you had to do to be able to come golfing this weekend. What's the deal?'

Fourth guy:
'I just set my alarm for 5:30am. When it went off, I gave the wife a slap on the ass and said: 'Golf course or intercourse?' She said: 'Wear sun-block."
