The Ecphorizer

Modern Millie, turned switch-hitter
Made it with the baby-sitter.
Hubby Harold, mistreated, blue,
Made it with the sitter too.
Rub-a-dubbing night and day
Made Harold and Millie old and gray
Before their time.
Sad to relate
The woes of those who fornicate,
Who defy nature, play the clown
And turn the sexes upside-down.
The only winner in the end?
That lucky baby-sitter, friend.
