My cells are same as your cells,
Your cells are same as mine.
If you don't mind me sayin',
I think your ass is fine.

You've got our Mummy's body
You've got our Daddy's eyes.
But where, oh, where di you get
Those breasts of such great size?

Get the incestating mug.
When two family members of the opposite gender have sex, resulting in the creation of a tyrant.

When you do it with your sibling of the opposite gender, your child will most certainly become a tyrant or live a life of suffering. Adolf Hitler was inbred, his dad fucked his niece, resulting in an incarnation of evil. Caillou is also inbred, he screams constantly at the littlest things and is just a general bitch, I mean why the fuck else would his parents names rhyme? If you do it with your cousin, there`s only a 50% chance it will be a piece of shit. Porn always features incest, somehow people find it hot, therefore, it is the fault of the porn industry that incest has become ever more prevalent! Even the bible (the biggest piece of horse shit in the galaxy) is against inbreeding!
Kevin: Oh god! What are Jack and Ellen doing in there? They`re siblings!
*Kevin bursts the door open*
Jack: Kevin, what the fuck? We were having sex!!
Kevin: I`ll tell you what the fuck, you guys are doing incest!
Ellen: So?
Jack: Yeah, people do it in porn, so it`s perfectly fine!
Kevin: You trust that shit?
Jack: Yes, of course I do!
*Jack and Ellen keep fucking each other*
Jack: I`m cumming! Uuuuuuuuuuuuunnhhhh!!!
*9 months later*
Ellen: Let`s name him..... Caillou...

*Disclaimer: I do not condone incest or inbreeding, inbreeding can be very dangerous for you and the child, you don`t want your child to become like Hitler or Caillou after all.
