Vegemite is good for anything. A hangover, a grumpy a child, a bad day, cheese. Australians don't know how to get up in the morning without a glass jar of the black yeast paste nearby to smother on a bit of bread and devour like nobody's business.

As the rest of the world screws up its nose in disgust at the stinky glug, Australians eat it by the bucket load with a smug look on their faces. It's a party only Australians are invited to. You can have it on a SAO, you can have it on toast, you can have it straight from the jar on a spoon and now, you can have it stuffed into your pizza crust.

It is moments like this history is made. When life changes forever and pizza will never again suffice with prawns alone. Introducing Pizza Hut's Mitey Stuffed Crust: a perfect recipe of Vegemite and mozzarella cheese melted and shoved into the crust. Australia, your Hawaiian will never be the same.

And the tourist guinea pigs used in the commercial by Pizza Hut also will never be the same. The mystery substance hidden in a pizza crust was fed to them at a backpackers hostel in Bondi Beach, Sydney. The reaction is the reason every Australia will want to eat 20 of these local-only pizzas — the tourists, who clearly haven't learned a dash of Aussie culture, are absolutely horrified at the "medicine, petrol, fish thing" they just allowed into their foreign mouths.

You wouldn't understand. It's an Australian thing. (Even New Zealand had to suffer through a marmite version).

Smart play, Pizza Hut. Looks like we're staying in this Australia Day. Pass the pepperoni and vegemite.
