Traits

I enter the bedroom, plop down on my husband's stomach, and start kissing his face.
Me: *smooch smooch smooch*
Bizarro Dad: Okay, okay, I get it. You love me.
Me: Of course I do.
BD: It's all a front.
Me: What is? My kissing you?
BD: Your loving me. You only love me because you love my beautiful-baby-producing ability.
Me: So you're saying I only love you because I... love you? And because we made pretty kids?
BD: Yep, that's right. You said, "I think that's the one with the right genes."
Me: (giggling) You got me honey. I sat down and made a Punnett square and determined that all your most desirable features that I liked would be dominant, and all the ones I didn't like would be recessive to my dominant ones. Thus we would reproduce highly attractive offspring.
BD: I knew it.
Me: Unfortunately, Sia accidentally inherited your tiny-butt gene.
BD: Well, they can't be perfect.
Me: And it's probably better that way. Can you imagine how much trouble we'll have with her as a teenager if she has a big ass?
BD: Terrible, I tell you.
Enter Sia, who climbs onto our bed.
Me: Hi sweety.
BD: Poor baby, what did I do to you? You don't have a butt.
Sia: (putting hand on her butt) It's right here, Daddy.
