Mmm... mayonnaise!!!

A man and his four year old son are talking when his son asks "Dad, what does a pussy look like?" Confused, the Dad asks him "before or after sex?" The kid says "Ummm... before sex". So the dad says to him "Well have you ever seen a beautiful red rose with soft red pedals." "Yeah" says the son. "Well what about after sex?" he says to his dad. His dad replies "Have you ever seen a bulldog eating mayonnaise"
