Nothing to worry about !

In a second grade sex education class, Susie asks her teacher:

Susie: Teacher, can my mummy get pregnant?

Teacher: How old is your mother?

Susie: Forty

Teacher: Yes, your mother could get pregnant.

Susie: Can my big sister get pregnant?

Teacher: How old is your sister ?

Susie: Nineteen

Teacher: Oh my.. Yes! Your sister certainly could get pregnant!

Susie: Can I get pregnant?

Teacher: How old are you?

Susie: I'm seven years old.

Teacher: No, you can't get pregnant.

Little Johnny gives her a poke and says: See?... I told you we had nothing to worry about!!!
