I came up behind a pickup truck, hogging the left lane, going 10 mph under the limit.

His tailgate read "You are following the leader". That's it, nothing else, no company logos on the truck, just "You are following the leader".

A little pompous, I thought to myself, seeing as how you are only leading anything by forcing people to get stuck behind you, which isn't really leading.

At the first open chance I got, I flew past him while yelling "Who's leading who now bitch!"

Not that he could hear me, as his windows were up, and so were mine, and we were traveling at 65 (or well I was...).
