DNA Test

After 10 years, the wife starts to think their child looks kind of 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 kid!
Husband: Well you don't’ remember, do you?? When we were leaving the hospital,
we noticed that our baby had pooped.
Then 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!!

Good one
Makes sense to me
