"Complaints" joke

A man was carrying two babies, one in each arm, while waiting for a
train.
Along came this woman seeing the two cute babies started asking the
man,"Aren't they cute, what are their names?"
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."
