A husband and wife decided to use a secret “code word” when they wanted to be intimate – so their child wouldn’t catch on. So together they agreed to choose the word “Typewriter.”

One evening, the husband asks his 5-year-old daughter, “Go tell Mommy that Daddy needs to type a letter.”
She ran off and told her mom, who replied, “Tell your daddy he can’t type right now — there’s a red ribbon in the typewriter.”

A few days later, the wife told the daughter, “Tell Daddy he can type that letter now.”
The little girl ran to her dad, then came back and said, “Daddy said never mind the typewriter – he already wrote the letter by hand.”
