I've always thought that Gieco missed the mark on their advertising. The Gecko is okay (mostly because of it's mysterious accent), but otherwise I've felt like their concepts are a little out there. Their new commercials though, are phenomenal.
The first, with the pig crying wee wee is pretty popular, but I actually didn't really get the humor until I saw the woodchucks, which I think are hilarious. Now that I get the humor I think the entire campaign is awesome- I wish I'd gotten it sooner.
Funny though, how some pieces of a campaign resonate with different people.
