You'll notice that they only show the ordering of the first one. They probably ordered a shitload of Maccas and made these themselves. Although I believe that McDonalds do have a policy where they will make most any burger to order - they just don't tell you that so people don't make a habit of it.
To be fair a lot of Maccies employees are probably stretched by creating the set menu, let alone various new combinations.
On another note, Crom help me I am actually starting to like a few of the people who comment on the news section.
I am getting that way as well. I am taking a liking to that Stewie guy. Not only can he be informative, but he can also be hilarious. I always look for his posts whenever I feel the random urge to view an article and give Ryan "C&P" Clark some clickage cash.
Hey.. I'm not telling you anything that you don't already know.
