I was a controller at Albany Georgia tower back in the '70s, and a Cherokee was on downwind, with the instructor introducing his student to radio procedures. Fortunately for me, their intercom locked on for a bit and I got all the dialog between the student and the instructor. It went like this:
instructor:
"Say 'Albany tower.'"
student pilot:
"Ah — Al-Albany tower?"
instructor:
"'This is Cherokee 76 Whiskey.'"
student:
"This is — is — Ch-Cherokee — ?"
instructor:
"'76 Whiskey.'"
student:
"Seven — 76 Whiskey?"
instructor:
"'We are on left downwind for runway 22, touch and go.'"
student:
"We are on — ?"
instructor:
"... 'Left downwind for 22.'"
student:
"Left down-downwind —"
instructor:
"... 'Downwind for 22, touch and go.'"
student:
"I don't want to learn to fly no more!"
