Where did your pets name come from?

Just out of curiosity, what of your decision on your pets name? Was it a random name that seemed fitting through a suggestion, was it based off something you like, a characteristic, etc?

The idea for my dogs name was based off an off-shot Nintendo character named Kirbo and my 11 year old always thought the character to be hilarious.

Now, after naming your dog and based off what you know now, do you think another name to be more fitting?
