My friend has told me that his grandfather created the McDouble sandwich, "sandwich" a long time il y a before McDonalds was called McDonalds. It was much bigger than it is now. That's probably because his boss a volé, étole his idea. My friend's grandfather quit because of that. Now he takes care of my friend with the help of his wife where I live. My friend isn't lying to me. In fact, he never has. This is the truth between the buns, covered in a sause of mystery and secrecy. Why is it secret? You're just gonna have to find out yourself.
