During my on the job training:
Me: (fresh from the simulator) Callsign, do you have the A330 now taxiing ...right in front of you in sight?
Pilot: Are you joking? Is there any way we wouldn't?
Me: Well..taxi behind. *bright red faced*
(overheard on the frequency)
ATC: Callsign(A330) hold short of the runway, light aircraft on final.
Pilot of A330: You expect a heavy to wait for the ppl?
to which the student pilot promptly replies
"A pilot is not born in the A330 sir."
A friend of mine, while on OJT, talking to a Swedish airline, coming direct from Sweden. (Location indicator starts with ES.. can't remember the exact airport)
Our language is Greek, but we use English at the RT.
ATC: Vacate the runway to the right, contact Ground xxx.x, Buenas Dias.
Pilot: *long pause* Erhm..To the right... buenas dias.
My friend was so proud, it took me a couple of minutes to stop laughing and explain to him that the location indicator ES was not for Espana = Spain.
