We already heard about the world's largest pizza party, but this gallery has pictures of some of the biggest pizzas in the world. It's not complete, since we don't know what some of you are doing in your homes when the record keepers aren't there to measure your creations, but it definitely gives you a reference point the next time you walk into a pizzeria that serves unusually large slices.

The world's record for largest pizza belongs to a 122.6-ft. pizza that was made in Norwood, South Africa in 1990. This monster pie used almost 10,000-lbs. of flour, 3,968-lbs. of cheese, 1,984-lbs. of tomato puree and 200-lbs. salt. For perspective, 4 cups of flour is the equivalent of one pound, and that would make plenty of dough for a large pizza. That means that the record setting pizza could have fed a slice or two to at least 40,000 people.

Apparently, Viacom International Inc., which owns MTV and produces the TV show Pimp My Ride, owns a trademark that covers the use of not only the phrase "pimp my ride" but of "pimp my." As such, they requested that the fantastic snack site formerly known as Pimp My Snack change its name. Without admitting any liability or other intentional wrongdoing, the snack-pimping gang changed the name so that their pimping could continue unimpeded. They can now be found at Pimp That Snack.

If you haven't seen the site before, they take normal snacks and reproduce them in huge (and delicious) proportions. We mentioned them back at Easter, but here are a few looks at what they've been up to recently. Be warned that you may have a strong desire to pimp snacks after hanging around the site:

The US Army celebrated its 231st birthday with cake. A very, very big cake. The ingredient list included 540 eggs, 100 pounds of flour, 30 pounds of butter, 30 gallons of milk and 30 pounds of sugar and it took 17 chefs about 1 week to create. How did it work? It was constructed from layered individual sheet cakes - 50 of them, to be precise. 35 gallons of icing were used to cover and decorate the cake. The finished product was 8.5 feet long by 3 feet wide and weighed more than 250 pounds. It was served at the Pentagon June 14th to approximately 1,500 people.

Elsewhere in the country, individual divisions had their own celebrations with even more cakes.

Granted, this cake - which is still very impressive - doesn't come close to rivaling the world's largest birthday cake, which was built last year in Las Vegas and used 30,000 half-sheet cakes and 40,000 pounds of frosting. The end result was a cake which weighed in at 65 tons.

There is one more cake close-up after the jump, as well as a picture of the world's largest birthday cake.

Though there has been some debate in the past about who makes the world's biggest burger, the Guinness Book of World's Records officiated at the weigh-in of a 29.5-pound burger at the Foxwoods Resort Casino's Fuddruckers restaurant. They granted the 18.5-in. wide by 8-in. tall burger the title of "world's largest commercially available burger." It costs $250 and must be ordered 48 hours in advance.

There is one burger that is said to be larger: the Mount Olympus burger at the Clinton Station Diner, in New Jersey.  According to the diner, it weighs 50 pounds. A look at what goes into it reveals why it is not classified as the world's largest burger - Guinness officiation or not: it only has 25 pounds of beef in it. Twenty-five pounds of toppings on a bun, even with meat, makes a salad and not a burger. The Fuddruckers burger, by contrast, started with 33 pounds of beef and, while it did cook down to about 25 pounds, there were only 4.5 pounds of toppings on the final product, making it meatier than the Olympus and more title-worthy.

Despite the fact that McDonalds has been receiving an extra-large serving of criticism recently, it hasn’t discouraged the company from doing what it does best: making burgers. While some customers turn away, others still look for size and value in their fast food and the new Bigger Big Mac, due to be released soon in the UK, will give them both. The burger is a full 40% larger than the regular Big Mac and, base on that, can be expected to pack at least 700 calories. It is a limited edition burger that is being targeted at football fans, so the release coincides with the 2006 World Cup. Spain and Germany are also likely to see the release of this bigger Mac.

If you have heard of In-N-Out Burger, you probably know that the Double-Double is their most famous sandwich. Its name derives from the fact that is has two patties and two slices of cheese. What you may not know is that you can order any size burger you like, from a 3x3 - three patties, three slices of cheese - on up. I personally witnessed someone attempting to eat a 6x6, but am forced to qualify the event as an "attempt" because the whole burger wasn't consumed in one sitting. Let's just say it wasn't a plesant viewing experience. The above picture is a 20x20 burger. la.foodblogging caught a rare sighting on camera: the 75x75, made just for you and 60 or so of your closest friends. In-N-Out charges for the extra patties and cheese, but I bet that if you get a burger that big and ask very nicely, they'll throw in a free order of fries. The employees will not be doing it because they expect you to eat them - just for the irony.
