Years ago I was taking the practical test for my initial CFI with and older pilot examiner. This gentleman was famous for an excessively high bust rate, and a charming personna to boot. Female applicants were often greeted with "I didn't know girls could fly, are you sure you're in the right office sweetie?" In the course of my oral examination, this august aviator asked me to explain how a spin is caused. I launched into what I thought was a brilliant dissertation on aerodynamics and stability and control as reletad to spins. As I was blathering on, the gentleman reaches into a drawer, inserts and then withdrawls his hand, now covered with a puppet....of a parrot. "RRHHAA!" the parrot sqwuaks, interupting me. In a shrill, parrot-like voice the bird continues: " Polly wants an answer in your own words! Quit parroting what the book says!" I bit my tongue to keep from laughing and continued. I passed. What a goob.
