Not sure why, but just remembered a joke from thirty years ago:
Q: What's the definition of a macho guy?
A: A guy who comes home at three in the morning, shakes his wife by the shoulder, and says, "Wake up honey, you're next."
Thirty years ago I found this joke absolutely hilarious. Looking at it now, in print, it doesn't seem quite as funny. Of course, there is no age at which women find this funny.
