After 10 years, the wife starts to think their kid looks kinda strange so she decides to do a DNA test.
She finds out that the kid is actually from completely different parents.

Wife: Honey, I have something very serious to tell you!๐Ÿ˜ฐ

Husband: Whatโ€™s up?๐Ÿ™‚

Wife: According to DNA test results, this is not our kid!!๐Ÿ˜ข

Husband: Well you dontโ€™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, Iโ€™ll wait for you here.
So I went inside, got a clean one and left the dirty one there!!!๐Ÿ˜
