What father doesn't croon about incest over sleazy electronic music while laying shirtless in bed with his kid? In a perfect world, fucking all of them.
There once lived a man named Oedipus Rex.
You may have heard about his odd complex.
His name appears in Freud's index
'Cause he loved his mother...
Yes, he loved his mother like no other.
His daughter was his sister and his son was his brother.
One thing on which you can depend is,
He sure knew who a boy's best friend is!
— Tom Lehrer, "Oedipus Rex"
Many a man before you, in his dreams, has shared his mother's bed.
— Jocasta (desperately trying to calm her son/husband down in the worst way possible), Oedipus Rex

And Lot went up out of Zoar, and dwelt in the mountain, and his two daughters with him; for he feared to dwell in Zoar: and he dwelt in a cave, he and his two daughters. And the firstborn said unto the younger, Our father is old, and there is not a man in the earth to come in unto us after the manner of all the earth: Come, let us make our father drink wine, and we will lie with him, that we may preserve seed of our father. And they made their father drink wine that night: and the firstborn went in, and lay with her father; and he perceived not when she lay down, nor when she arose. And it came to pass on the morrow, that the firstborn said unto the younger, Behold, I lay yesternight with my father: let us make him drink wine this night also; and go thou in, and lie with him, that we may preserve seed of our father. And they made their father drink wine that night also: and the younger arose, and lay with him; and he perceived not when she lay down, nor when she arose. Thus were both the daughters of Lot with child by their father.
Fuuma: Have you forgotten the first sword? It belongs to the Dragon of Heaven, but there's another sword. It belongs to the Dragon of the Earth. Ant it's inside of you. I must take what's mine!
Bennett: Guys... It just hit me... If his sister is his lover and she has a sword for him in his uterus, does that mean Bubbula's mother—AAAAAH--AAAAH--AAAAH!
Mifi: You perpetrated such acts upon your adopted daughter? Even a thousand years ago, wouldn't that just seem plain wrong on a personal level?
Elza: Well, try to think of it as a parent, though. When raising a magician, it's practically indisputably essential that you train them in the Lustful Arts. Their practical benefits cannot be honestly denied.
