After 10 years, a wife started to think their child looked kinda strange,

she she did a DNA test and found out that the child wasn't theirs.

She told her husband what she found out.

The husband replied,"You don't remember do you?"

When we were leaving the hospital, the baby pooped

and you told me to go and change him, so I went inside

and got a clean one and left the dirty one there.

The wife fainted!
