Joe Biden made a sex joke about his parents and grandparents today at the La Raza conference:
"My mother said, and by the way, it was wonderful for children by the way--having your grandpop living with you, having your great aunt, your uncle, for real," Biden said. "Those walls were awful thin, I wonder how the hell my parents did it! But that's a different story. I know you don't anything about that. I know none of you in your families have done the same thing."
