It's actually harder saying Jinjo to people it seems than looking at it! With the exception of one desk person at our vets that seems determined his name is "Jingo", when I tell people his name they automatically swamp him with "Ginger! Aren't you sweet!" *face-palm*
In any case, what I always end up telling people is "Gin-like gin and tonic, Jo-like GI Joe" with LOTS of emphasis on "Jo". Sad, I remember years ago in his agility classes someone use to always call him "Joe-sombody" because she couldn't remember the rest, lol.
But if that isn't enough, watch this video and you'll get about 50+ chances to learn how to say it properly:

Enda, I looked it up only after someone told me it's a real name, yeah I seriously just decided to shorten her registered name "Endless" and added an A at the end! Guess I'm not that creative, but it's fitting, it mean "Bird-like". Anyway, I say it "End-Ah".
Noodle...do I have to?
