A boy and his Chinese family went to the zoo, and they saw two monkeys having sex. The boy asked “What are they doing?” The parents replied “Making a cake.”
On the way home, they saw two poodles having sex. He asked “What are they doing?” “Making a cake,” his parents replied.
They all went to bed. In the morning, the boy went to his parents and said “Since you were making a cake last night, I went and licked all the icing off your bed.”
