True Story...
Back in my instructing days I taught a lot of foreign students (chinese/arab). One of these guys is flying the 337 solo while working on his commercial and as he returns to Oakland Intl he calls the tower
"Oakland tower, cessna 19EZ downwind 9L" (In chinese accent!)
Tower responds
"Was that last aircraft calling the Skymaster?"
Pilot "Ah, no I'm not the skymaster but my instructor says I am a very good pilot!"
