Ad number 1:
I remember a TV ad about some weight loss program of fitness club (can't remember the name of it, sign that I don't belong at all to their target audience) broadcasted around Thanksgiving. The ad showed a treadmill with its belt moving but nobody on it. The next thing you would see is a big plate with a whole roasted turkey on it being dropped and "crashing" on the belt, along with champagne glasses shattering.
This sort of ad would have provoked a huge uproar in France, where it would have been considered equivalent to throwing food on the floor and showing tremendous disrespect towards people who cannot afford to eat properly everyday.
The ironic thing is that the ad used some cheesy special effect (superimposing the image of crashing food on top of the treadmill), so that the fitness equipment would not actually receive all this food while the food would actually splatter on a surface (assuming the turkey was actually made of very convincing plastic or rubber, the other food around it looked quite real).
Ad number 2:
The ad, from a fast-food company, shows at the end a huge double- or triple-decked hamburger plopping on a white surface (doesn't splatter). The disgusting side of the ad, besides encouraging supersized burgers, is in the way it plops down pathetically like dog turd.
If one were to show a plopping hamburger (if ever) in Japan in a burger ad, one would have gone to great lengths to make the plop elegant and appetizing, sacrificing the realism of the turd-style plop in favor of an idealized, modified-motion version of it.
