My favorite airport advertising backdrop is in ORD/Chicago O'Hare. At the Manchu Wok, there's a lighted sign with a guy in a Manchu Wok uniform about to make a monsterous slam dunk.
At first blush, it doesn't seem to make much sense, but the player is actually an anthropomorphized fortune cookie. The cookie's paper fortune extends, serving as a tongue, MJ-style. The result: a 3-item combination of chinese food, sports and local lore. Nice.
