There are 60,000 names submitted each year to the racehorse naming rights authority, The Jockey Club.
Of those entries, nearly one third are rejected—mostly because the name is already taken.
But The Jockey Club has a long list of rules of how to name your horse. The name can't be more than 18 letters, can't use initials, can't be names of real people (unless you have written permission to use their name), can't be famous dead people or notorious people, and can't be a copyrighted name.
And most importantly, nothing vulgar or obscene.
With that said, it's amazing what has slipped by the "goalie," as they say, through the years.
Here's a look at some of the funniest and most interesting horse names—including an explanation for our cover photo.
