With the Kentucky Derby happening this weekend, one of the fun things to always do is look at the names of the racehorses. They're usually ridiculous. This year's favorite is Big Brown, which could be a euphemism for a number of things, like say what the horse left in the back of his stall before going out to race. Or it could mean absolutely nothing.

The more interesting thing though is that every racehorse name has to go through The Jockey Club - based in New York and Kentucky - for approval. Generally speaking they try to reject offensive, suggestive, or obscene names. So if Big Brown was named Big Brown Deuce, his name would probably get rejected. But here's the fun thing, they don't always reject everything.

So here's a look back at real racehorse names that were actually signed off by The Jockey Club. So you know, not all of these names below will appear in the current registry, because the registry lists primarily recent names. If you want a full perspective, you'll need to shell out $325 for the complete American Produce Records to see everything the Registry has approved. Anyway, most of these names are dirty, while a few others are drug related or just strange. Lord only knows how some of these names were approved.
