I m just joking!

Михаил Салита
One woman, named Kira
Told her husband in tears:
-The child should be tested for DNA for sure.
 And suddenly he is not ours, dear!
This made her husband laugh about she told
And he is not surprised at all:
-Do you remember in the hospital you said
  The child crap one's pants, change for clean one?
  Then I took our son
  And change for next lay child clean one.
 Stop! I'm just joking!
 About what are you talking?
