Evidently, Marmite never really caught on in North America. I don't really know how this spreadable yeast extract tastes, but I do know that I enjoy these Marmite ad spoofs.

While launching their new cereal bars, this illustrious company went ahead and launched a campaign that scared people into thinking they were going to do something really drastic, like launch a shower gel. Itthen calms your mind while informing you that it is just cereal bars. Marmite ad spoofs win.
