The wife came home early...

...and found her husband in their bedroom making love to a very attractive young woman and was somewhat upset.
'You are a disrespectful pig!' she cried. 'How dare you do this to me a faithful wife, the mother of your children. I'm leaving you. I want a divorce straight away.'
And the husband replied 'Hang on just a minute love, so at least I can tell you what happened.'
'Fine, go ahead,' she sobbed, ' but they'll be the last words you'll say to me!!
And the husband began - 'Well, I was getting into the car to drive home and this young lady here asked me for a lift. She looked so down and out and defenseless that I took pity on her and let her into the car. I noticed that she was very thin, not well dressed and very dirty. She told me that she hadn't eaten for three days! So, in my compassion, I brought her home and warmed up the enchiladas I made for you last night, the ones you wouldn't eat because you're afraid you'll put on weight.
The poor thing devoured them in moments. Since she needed a good clean up I suggested a shower, and while she was doing that I noticed her clothes were dirty and full of holes so I threw them away. Then, as she needed clothes, I gave her the designer jeans that you have had for a few years, but don't use because you say they are too tight.
I also gave her the underwear that was your anniversary present, which you don't use because I don't have good taste. I found the sexy blouse my sister gave you for Christmas that you don't use just to annoy her, and I also donated those boots you bought at the expensive boutique and don't use because someone at work has a pair the same.'
The husband took a quick breath and continued - 'She was so grateful for my understanding and help and as I walked her to the door she turned to me with tears in her eyes and said, ' Please do you have tree fiddy?'
