Paternity test
For those of us who sat through all required biology classes in high school, it might seem obvious to us that when a set of triplets are born, they all have the same father. One “helpful” man, though, decided there were questions over paternity because his friend’s wife had just given birth to one triplet who was slightly darker-skinned than the other two.
Not only did he have some questions, which he could have kept to himself, but he decided to confront the wife first, who was understandably mad. That not being enough, he then spoke to his friend. I’m not sure I would have been friends with the guy for very much longer. He also needs to do a bit of biology research.
