When a man is young, he may dream of going camping, meeting a young woman who wants him, and spending the entire trip... well, you know.
When the man gets a little older, he needs more stimulating fantasies. He may dream of going camping and meeting
two young women who want him, and... you get the picture.
When the man gets old, he's likely to dream of going camping and meeting
three women who want him... as a partner in a foursome of euchre!
