Search: McDonald's now serving lamb burgers

Earlier this month, fast food chain McDonald's introduced its latest creation: the "Serious Lamb Burger" in Australia (watch a commercial for it).  The new sandwich contains one lamb patty, an egg and aioli sauce (see photos of what goes on top of it).  The company also unveiled a giant billboard to promote the burger (find out how many calories it has) that features a classic childhood rhyme (see what it says).
