After 10 years......
After 10 years, the wife starts to think their child looks rather strange, so she decides to have a D.N.A. test done.
As she suspected, she discovers the kid is actually from completely different parents.
So, she decides to ask her husband about it.
Wife: “Honey, I have something very serious to tell you.”
Husband: “What's up?”
Wife: “According to D.N.A. test results, this is not our kid.
Husband: “I guess you don't remember, do you? When we were leaving the hospital, you noticed that our baby had pooped, and you said: "Please go change the baby; I'll wait for you here."
So, I went inside, got a clean one and left the dirty one there.”
Moral: Never give a man a job for which he is not qualified.
