I heard a good one the other week, asian student pilot vs. Auckland tower:
"Auckland tower whisky hotel yankee, cessna 172, overhead XXX request enter the control zone for touch and go"
"Whisky hotel yankee, Auckland tower, squawk ident"
(Long pause)
"Auckland tower whisky hotel yankee, cessna 172, overhead xxx request enter the control zone for touch and go"
"Whisky hotel yankee remain clear of controlled airspace, squawk ident"
(another long pause)
"Auckland tower whisky hotel yankee, Cessna 172, overhead ... "
Variations of this went on for a good few minutes, the poor guy had obviously no idea what a transponder was, but the punchline came from a jet jock who'd been listening to the whole ordeal
"Auckland, NZ XXX 3000 feet on visual approach, and that's a most appropriate callsign that guy's got"
"NZ XXX join left base, descent unrestricted, and amen to that!"
