I bet they were big hairy assed Nephlim with six toes on each foot and an extra testicle case they lost one in a fight!
I think the story about Noah and lot are too similar for coincidence...besides who names their boy Shem..that's a girlie name.
Noah: Shem have you fed the elphants and giraffes today.
Shem: Dad would ya please put your clothes on and No I haven't, Ham and myself just threw those damn Horny Unicorns overboard...sneaky bastards goosed ya with that cubit long ribbed horn everytime ya walked by...oh sure it was fun once or twice but come on.
