DNA test jokes
Wife
After 10years a wife started to think their child looks kinda strange so she did a DNA test and found out the child is not 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 got a clean one and left the dirty one there.
