Odd little fact I found out today (connected to unhealthy fast food), turns out that McDonalds don't actually use egg logs in their breakfast foods.
For those who don't know, an egg log (and if anyone can find me a website with adequate information of said log I'd appreciate it because Google is turning up nothing) is basically... well a log of processed egg which fast food establishments would cut up into little discs and fry them for their breakfast foods (see Clerks 2 to see it in action). Judging by the perfectly circular lumps of egg that seem to come with the McDonalds breakfast foods such as the sausage and egg mcmuffin, it would be reasonable to assume that they use such techniques.
But, it seems McDonalds (this being confirmed by ex-employees) actually uses real eggs and an odd system of making them round and thick to fit the muffin. Who knew, McDonalds actually cares... a little... about their food.
