There's a Facebook group dedicated to one air traffic controller named Michel who says "Rodge" on the radio in acknowledgment of calls. He's currently working for Toronto Terminal. Air traffic controllers are supposed to, and for the most part do adhere to very strict limits of procedure and terminology such that there shouldn't be an operational difference between the experience between being handled by one or another. But this guy reveals just a bit more personality than most and has what amounts to a cult following among pilots. The Facebook tributes to this guy have built into aviation-themed Chuck Norris jokes. His bosses must hate it.
