Did… did he date his children? Or do you mean he killed them all?

Killed his whole family

All his kids are blonde… and neither parent is… Is that intentional?

No but it is possible to have blonde kids from brunette parents if both parents have dominant allele for brown hair (manifests as brown hair) and a recessive allele for blonde hair (doesn’t manifest, they’re carriers of this recessive allele)

I passed 9th grade science, I know how genes work. I thought that was the unintentional joke.

1st: after
2nd: before

1st is also before. He killed his wife too
