World's Priciest Hamburgers

Tired of the same ol' Big Mac? Try biting into one of these burgers, smothered in fancy goodies that make them the most expensive beef patties in the world. The Huffington Post rounds them up:

• Absolutely Ridiculous Burger, Mallie's Sports Bar & Grill, Southgate, Michigan, $499: This behemoth weighs in at 185.6 pounds, and it holds the Guinness World Record for Earth's largest hamburger.
• 777 Burger, Le Burger Brasserie, Las Vegas, $777: Caramelized onions, Brie, and prosciutto sit atop a patty stuffed with Kobe beef and Maine lobster. Why $777? It comes with a bottle of Rose Dom Perignon champagne.
• uSocial Burger, uSocial ad agency, Australia, $10,000: This burger is being auctioned off for charity. It features sliced white truffle, 24-carat gold leaf, and a rare Spanish ham made from free-range Iberian pigs. You can actually bid on it here, but you'll need 10 grand to start.
