One day a mother and her five year old daughter are walking through a park when they come across two teenagers having sex. The daughter asks, "Mommy, what are they doing?" The mother replies, "Making cakes." The next day the mother and daughter go to the zoo. The daughter see's two monkeys having sex and asks her mom what they're doing. The mother replies, "Making cakes." A week later, the daughter comes running into the kitchen screaming, "Mommy, mommy, mommy, you and daddy were making cakes in the lounge last night, weren't you?" The mother, mortified, asks, "How do you know?" The daughter says, "Because I just licked the icing off of the sofa."
