according to the alaska department of fish and game, both male and female reindeer have antlers, the only species of pointy-headed mammal to have accomplished that on both sides of the gender. however, male reindeer usually lose their antlers in late november/early december. also however, the female doesn’t lose its antlers until after giving birth. so there’s a good chance that not only are santa’s reindeer all female, but they could also be pregnant.
there’s a potential for some really nasty road rage.
