hehe, good one Interman
ok, here's mine:
A girl and her mother were walking through the park one day and the little girl saw a man a women kissing. The little girl asked:"Mommie what are they doing??" The mother replied:"Baking a cake".
Later that day, the girl and her mother were in the cinema. A small sex scene came on. The little girl asked:" Mommie what are they doing?". Again the mother replied:"Baking a cake". The next morning the little girl told her mother:"Mommy, you and daddy were baking a cake yesterday" The mother asked the girl how did she know. The little girl replied:"Because I licked the icing off the couch"
