It might have been something about idiots who only clean off their windshield enough that they can see out. not the passenger side, or the sides, or the back. Real safe, man.
Or those who do clean the windows off but leave a foot and a half on top which flies off as they drive in front of you causing a localized white-out. That's great too.
Or how I can't watch a Canucks game on Sportsnet Pacific because it's blacked out. But I'm in ONTARIO!!
I know it wasn't any of those things but I still can't remember. It will come to me tonight and work and I'll forget again by the time I get home.
