Baking

A little boy caught his mom and dad having sex. After, he asked, "What were you and daddy doing?" The mom said, "We were baking a cake." A few days later, the little boy asked his mom, "Were you and daddy baking a cake?" She said yes, and asked him how he knew. He answered, "Because I licked the frosting off the couch."
