One day a little girl was watching cartoons when a porno came through. The little girl asked her mom "What are they doing?" The girls mom said "baking a cake."

Then the next day they were walking in the park and there were these people making out and the girl said "look mommy they are baking a cake!"

The next day the girl says "mommy you and daddy were baking a cake last night."

Her mom replied "how did you know?" The girl said "because I licked the icing off the sofa!"
