Messing up men

We found a new way to tease men. Ask them these questions in this order. What they answer doesn't matter that much:

Do you have children?

Do you want children?

What kind of a woman do you want to have children with?

If you liked me enough, would you want children with me?

Do you want to get to know me better?

Let's do that now! I'm pregnant. And you are... ?

Here they get crazy and they always believe you're pregnant!
