Ok just lets give this one to the males. Just to make them happy. When deep down we know all Santa's reindeer were female.
1. When girls are grouped together they never ask for directions. Because being out with the girls is just fun and we are never lost we are just in a new place to be found thats all.
2. We females had to make the lead reindeer with a male name so all you males didnt get a hit in the ego. Besides I have seen many girls with the shorten version of the name Rudolph - you know Rudy.
