Those annoying drivers that we seem to get behind every morning on our way to work that are going 5 mph slower then the speed limit.

Tourists that are site seeing and causing traffic backups because they are going 5 under the speed limit.
Sorry I'm late boss. I got behind two 5 unders on my way in this morning.
