How did you name your dog?

I ran across a 'Net post the other day about someone who had bet $20 on the Kentucky Derby one year and, after winning the bet (on a long shot), they used the money to buy a dog... Thus they named it "Derby".
Then, a couple of days later I met a woman in PetsMart who had an Peekapoo puppy, which she called "Pikachu." She said her kids were crazy about the cartoon and she liked the way the names rhymed.
In our business we run across a huge variety of dog names, but these two really tweaked my curiosity about how other owners name their pups.

For us, Jay, Lance, and Princess Francis were all named by their previous owners and/or rescue center (though we do refer to Princess as "Hurricane Francis" from time to time!), and we didn't want to confuse them by changing their names. Mia didn't respond to any name when we got her from her abused situation, and we literally spent 2 days calling out female dog and human names to her until we found one that made her wag... she chose her own name.

So how did your dog get his or her name?
