Once a young boy was watching his mother take a bath. As she got out to dry off, he notices her upper torso he asks
"Momma what are those?" She replies
"Son those are my breasts," as she turns her back to him he asks "Momma what is that?" she replies
"Son that is my derriere." As she turns to slip on her robe he spies her nether region and asks
"Momma what is that?" She replies
"That son is none of your business!"
Later the boy is playing by the kitchen door, and the father comes in from work hungry.
The father hollers toward the kitchen to the mom, "Hey honey, what's for dinner?" She replies
"None of your business."
The son shaking his head says "YUCK!"
