Condom factory jokes

Condom

The popular girl told me, "I bet your birth certificate is an apology letter from the condom factory!"

Two weeks later, she shows up pregnant.

I guess her rubber broke too.

Birth Certificate

Little off topic but...

Mum: You wouldn't be here without me.

Son: And my birth certificate is a sorry letter from the condom factory.

Mum: Fair point.
