After 10 years,
the wife starts to think their child looks strange so she decides to do a DNA test.
She finds out that the child is actually from completely different parents.
Wife: Honey, I have something very serious to tell you
Husband: What’s up?
Wife: According to DNA test results, this is not our child.
Husband: Well you don’t remember, do you? When we were leaving the hospital, we noticed that our baby had wet its diapers and you said, "Please go change the baby, I’ll wait for you here." That's when I went inside, got a clean one and left the dirty one there.
*Moral* : Never give a man a job that doesn't belong to him.
