let mans: LivingThings.Human[] = [];
let hu = new LivingThings.Human(new LivingThings.HumanName("Ron", "Joopeppbpbppbbp"), LivingThings.Gender.Male);
mans.push(hu);
let danky = new LivingThings.MemeHuman(new LivingThings.HumanName("h3h3", "productions"),LivingThings.Gender.Male, LivingThings.MemeHumanType.MansNotHot);
mans.push(danky);
mans.forEach(man => console.log(man.generateMessage(`${man.name.first} not Hot`)));

also the data that is there is very inaccurate
