Making Cakes

There was a little girl and her mother walking through the park one day and they saw two teenagers having sex on a bench. The little girl says, "Mummy, what are they doing?" The mother hesitates, then quickly replies. "Ummm.....they're making cakes!"

The next day they are at a zoo and the little girl sees two monkeys having sex. Again she asks her mother what they are doing and her mother replies with the same response, "making cakes."

The next day the girl says to her mother, "Mummy, you and Daddy were making cakes in the living room last night, weren't you?" Shocked, the mother says, "How do you know that?"

She says, "Because I licked the icing off the sofa."
