A friend who instructs told me of a student he once had. The student was on his second or third flight ever and the instructor told him to contact ground for clearance. He told the student, "Tell ground who you are, where you are, and what you want to do, and the atis information." The student pauses for a second to rehearse in his head and then keys the mic and says "ground control... this is Jake... I'm in prescott arizona and want to get my private pilots license... with the atis information." ATC comes on freq laughing and says "Jake who is your instructor?" Without hesitation the student keys the mic and in the background you can hear my friend yelling at his student to let go of the mic key.

True story, and if you didn't catch it, Prescott Arizona is home to the world's finest flight school, Embry-Riddle.
