A woman enters the bus with her two children, the only places available are next to a man who seems very drunk, she sits with the children and the drunk man says: Your children are very beautiful.
She looks at him with disdain and says: Thank you.
You’re welcome, says the drunk. After a few minutes the drunk asks: Are your children twins?
The woman responds rudely: No, you can see clearly that one is much older than the other.
The drunk looks at her very thoughtful and says: Sorry I just find it hard to believe that someone had sex with you twice.
