For those of you who fall into the latter category, here's why...
I suppose it would have to start with a great board game called The Settlers of Catan (online version here), published by Mayfair Games. The goal of this game is to be the most successful player to settle the island of Catan, by building developments and trading resources. Of these resources, usually the most common in a regular game is sheep. Oftentimes, players will have more sheep than they know what to do with, which they can trade to the bank for another resource at a rate of 4 to 1. Usually when we play, we refer to this as "mulching sheep." In our minds, the sheep are not so much traded as they are used for a wildly inappropriate purpose, such as being turned into a road.
Enter CiderJack Hard Cider. They ran a radio commercial (available here as an mp3) a few years ago involving a man who was obviously in a beastiality chat room. In the background you can hear someone ask "Do you like sheep? I like sheep." After that, whenever we were playing Catan and needed a fourth sheep to mulch, we'd always ask, "Do you like sheep? I like sheep."
When we wanted to get a domain name that was fun and a bit unusual, this was our first choice. Amazingly, it was available, so we got it. And the rest, as they say, is history. Amusingly, about a month or two after we bought ILikeSheep.com, someone bought ILoveSheep.com, hoping to sell it to us. We weren't quite ready to move to that next level of sheep affection, though.
