"Why I fired my secretary" joke

One man explaining to another why he fired his secretary:
"Two weeks ago," I said, ''was my forty-fifth birthday and I wasn't feeling too
hot that morning anyway. I went into the kitchen for breakfast knowing that my
wife would be pleasant and say 'Happy Birthday' and probably have a present for
me. She didn't even say 'Good Morning' let alone say 'Happy Birthday'.
''I said to myself 'Well that's wives for you. The children will remember.'
But the children came into breakfast and didn't say a word. And when I started
to the office, I was feeling pretty low and despondent.
''As I walked into my office, Janet said 'Good Morning, Boss-Happy Birthday'
and I felt a little bit better that someone had remembered.
''I worked until noon. About noon, Janet knocked on my door and said, 'You know
it's such a beautiful day outside and it is your birthday, so let's go to
lunch, just you and I.' I said, 'By George, that is the greatest thing I have
heard all day. Let's go.'
''We went to lunch. We didn't go where we normally go, we went out into the
country to a private place. We had two Martinis and enjoyed lunch
tremendously.
''On the way back to the office, she said, 'You know, it's such a beautiful day
we don't need to go back to the office, do we?' I said, 'No, I guess not.'
''She said, 'Let's go by my apartment, and I'll fix you another Martini.'
''We went to her apartment. We enjoyed another Martini and smoked a cigarette
and she said, 'Boss, if you don't mind, I think I'll go into the bedroom and
slip into something more comfortable' and I allowed her as I didn't mind at
all.
''She went into the bedroom and in about six minutes she came out of the bedroom
carrying a big birthday cake followed by my wife and children. All were
singing 'Happy Birthday' and there I sat with nothing on but my socks.''
