I thought "the Pittsburgh Left" was funny. 20 years ago, one of my good friends ended up in Pittsburgh after one of his peripatetic wanderings. He had several amusing stories, mostly about adjusting to life in the big city--the Twin Cities were still stuck in a Mayberry timewarp, apparently. He described the "Pittsburgh Left" as a common traffic maneuver. We've finally caught up--I see it around here quite often--but I didn't realize it was commonly referred to as "the Pittsburgh Left."
