A girl and her mom go to the zoo. When they arrive at the monkey
section they notice two chimps fucking. The girl goes up to her
mom and askes her mom what are they doing. The mother thinks for
a while and tells her that the are making cupcakes. The mother
quickly takes the girls hand and walks away from the cage. The
next day the girl and her mom are sitting on a bench at the
park. They look across the road and notice there are two
teenagers having sex in the bushes. The girl surprised askes her
mother what the are doing. She quickly answers they are making
cupcakes. The mother picks up her daughter and runs home. The
next day the girl goes up to her mom and tells her that she knew
her and her father were making cupcakes the previous night. The
mother surprised asks her how she knows this. The girl looks at
her mother and answers, "I licked the frosting of the bed."
