I played an aarakocra in a campaign with a brand new DM once. I triple checked and told them some of the difficulties of having a flying character and I still got greenlit. Very first quest I flew to the top of a mansion and threw down some rope. Poor DM never saw it coming and I derailed the entire thing lol. I got up to all kinds of stuff that campaign and the DM did eventually figure out how to work with my nonsense
