Weird Holidays: An Article 19 Poll
As you may or may not know, today is National Sandwich Day. As I was just gearing up for a sandwich question to ask, I learn that it's also National Cliche Day.

So in the comments I'd like to ask you for your best sandwich memories--alltime favorite, or most interesting, whatever. But please, express as much of your comment in cliche as possible. We want to be respectful of all holidays here.
