Totally unrelated story, but there is a well known resterant here in Boston that serves customers until 4am.  Most people go to get pizza and rice balls.  There is a man who works the door who often wears a denim jacket, denim jeans and a denim shirt.  A friend of mind got into it with this dude one night (the guys a prick) and blurted out "triple denim" in the heat of an argument.  I think he was like "calm down triple denim, you're going to hurt yourself pal". Something to that effect.  This guys is only a double denim, which is obviously still a very exclusive club to be in.
