Who does the 'creative' for Subway ads?

What's the deal with Subway's ad campaign that features animated monkeys making sandwiches in some bizarre industrial setting? I'd hoped it would die a quick death, but they've kept it on air for more than a year now. They must have paid a lot for the animation.

I want to know: has a single person, anywhere, decided to buy a sandwich on the basis of this campaign?

Two things:

1. I don't really want a sandwich if it's made by -- or with -- a monkey.

2. If I really have to, I would prefer that the monkey that makes my sandwich not smoke a cigar while putting too much lettuce on the turkey, know what I mean?

Seriously, they have focus groups for a reason.
