SOUTHGATE, Mich. -- A Southgate restaurant owner believes he has broken the world record for "largest hamburger commercially available."

After 12 hours of preparation and baking, the 134-pound burger emerged Saturday at Mallie's Sports Bar and Grill.

The "Absolutely Ridiculous Burger," made with beef, bacon and cheese, was delivered on a 50-pound bun. It sells for $350, and orders require 24 hours' notice.

Flipping the burger required three men using two steel sheets.

Owner Steve Mallie said he wanted to show that he has the biggest and best burgers.

Authenticating Mallie's claim could take a few weeks. His burger would outweigh the 123-pound burger made last year by Denny's Beer Barrel Pub, of Clearfield, Pa.
