T-Rex: Guys, it's not hard to stay fully unknowable even to yourself. There's an easy way to go through life and still have mysteries. All you have to do is...
T-Rex: ...donate some friggin' sperm!
T-Rex: Find a program where they don't inform you when your sperm is used, and you're done! From now on, you'll NEVER KNOW if you've got a particular descendant - a child! - running around. People will say, "Hey, do you have any biological descendants?" and you'll be able to say "Man, WHO KNOWS??" Plus, you've done it all without the hassle of unplanned pregnancies!
Utahraptor: And this is appealing, T-Rex?
T-Rex: Oh yes! Entirely.
T-Rex: Wouldn't you love to be able to imagine every stranger of a certain age as your child? Utahraptor, it's a guaranteed sense of wonder for the rest of your life!
Utahraptor: That's kind of cool, actually.
T-Rex: I know! And it's all thanks to sperm!
God: T-REX DO YOU KNOW HOW MANY TIMES YOU'VE OFFERED "DONATE SOME FRIGGIN' SPERM" AS A SOLUTION TO AN APPARENTLY INSOLUBLE PROBLEM
T-Rex: Sixteen times?
God: THAT IS
God: AMAZINGLY
God: PRECISELY CORRECT
