Gecko

A friend of mine asked me, "why does that Gecko have an English accent"? You know the one on that insurance ad?
So, I looked it up on google. It said it was to make it seem friendlier.
Then I started thinking about that...I never saw a Gecko until I moved to the south. So, why not have a southern drawl?
Couldn't that be friendly? Just a little something from a bored mind.
