A couple had a red-headed baby

On her first post-delivery visit to their OB-GYN, the young wife asked if the doctor might help them with some confusion and anxiety. She explained to her doctor, “See, my husband and I are both dark, with dark hair. Everyone in both our families is dark. How can we have a red-headed baby?” “Well, there’s lots of reasons.” “See, I’m worried that people might think things about me, you know, wonder about it.” “You conceived sometime in March, so before, how frequently were you and your husband having sex?” “Not at all! He was deployed!” “How long?” “Eleven months!” “Ah ha! You were both just a little rusty.”
