I like to tell them I failed the PA+50 test - it’s a test to assess one’s ability to talk to large groups of people on the aircraft’s PA system and well , I got a bit nervous and started to stutter a bit , and failed. You can only take the test once every 10 years , so it’s cargo while I wait - someday I’ll be a commercial pilot ! Chances are they’ll tell that to 10 people and look like a complete doouchebag.
