Over the rooftops...........

According to the Alaska Department of Fish and Game, while
both male and female reindeer grow antlers in the summer
each year, male reindeer drop their antlers at the beginning of
winter, usually late November to mid-December.
Female reindeer retain their antlers till after they give birth in
the spring.

Therefore, according to every historical rendition depicting
Santa's reindeer, every single one of them - from Rudolph to
Blitzen - had to be a girl.

We should've known.

Only women would be able to drag a fat man in a red velvet
suit all around the world in one night, not ask for directions,
and not get lost.

(Shame on you, Santa! Expectant mothers should not have to work so hard!)
