The man gave the lady an angry look and replied, "I don't know."

The lady asked again, "Which is the boy and which is the girl?"

The man looking angrier than before replied, "I don't know."

The woman then started to scold the man, "What kind of a father are you?"

The man replied, "I am not their father, I am just a condom salesman and these are two complaints that I am taking back to my company."
