Two 'large' men smuggled electronics in between their rolls of fat.

Surveillance video from a Wal-Mart in Oklahoma shows the men scanning the aisles and focusing on the locked cabinet for about 15 minutes.

They return to the empty photo department with a shopping cart and a backpack.

“They get them in a backpack and take them to an area that is not observable by cameras. They take them out of the packages. They left the packages and went out of the store, through the checkout line. They did pay for some smaller items.”

Store security found those empty boxes shortly after the men left the store.

Investigators said they suspect the men used their girth to smuggle out thousands of dollars in stolen merchandise.

Authorities as asking the public for help identifying the "large" mystery men.
