If they say, "I'm going to go over a few things" before they even look at the release, you know it's gonna be wild.

One time on a MEM-NRT run the captain (he's infamous) gathered all three f/o's together at the counter to explain how to run the FMS - no abeam points, no VOR radials, etc.... Also no chewing gum in the cockpit. This before we've even spent a minute getting to know each other. Priceless...
