I was thinking the dad was maybe supposed to be Joseph, because he was a virgin dad, at least with Jesus. I think this is in fact possible. If losing your virginity is considered to be penile vaginal intercourse, then you could still have children. You could donate your sperm to someone or I guess artificially put it in. Okay, enough of that. This was a nice cartoon with all the good animation as usual.
My favorite part was the little girl talking about sex. That just struck me as hilarious. The voices are all nicely put up. I've always found it a funny concept to eat your hair. I guess it might just be because I play with my hair a lot.
