A husband and wife decided they needed to use "a
code" to indicate that they wanted to have sex without letting
their children in on it.
They decided on the word "typewriter."
One day the husband told his five-year-old daughter, "Go tell
your mommy that daddy needs to type a letter."
The child told her mom what her dad said and her mother responded,
"Tell your daddy that he can't type a letter right now because
there's a red ribbon in the typewriter."
The child went back to tell her father what mommy had said.
A few days later the mom told the daughter, "Tell daddy that he
can type that letter now."
The child told her father, and then returned to her mother and
announced, "Daddy said never mind with the typewriter, he already
wrote the letter by hand."
