Chicks on Maury who REALLY don't know who their "baby daddy" is
Dudes who make up lame excuses to deny their kids (i.e., "I fell off my bike when I was 7, so I'm sterile"; "I don't make boys/girls/handicapped kids/blue-eyed babies/natural haired babies/etc."; "The doctor told her that she was due on May 8, but she had the baby on May 4, so it's not mine!")
