I guess this will be some kind of a record, but I don't even want think about how many calories this is!
A man in Wisconsin put together every sandwich on McDonald's menu to build a "McEverything" sandwich. The total bill was $140.33 including tax, with $1 more for a diet coke. He used bamboo sticks to assemble the creation, and posted pictures with details on his blog "Dude Foods" at http://dudefoods.com/the-mceverything/
By arriving just as McDonalds was switching from breakfast to lunch, he was able to order from both menus. He says he has leftovers to last him for days.
