Pilot taxying in, on tower frequency:
"Tower, This is *****, taxying in. This was the last flight of my career; I'm retiring now. I'd just like to say thanks for your help and I'd like you all to know that you are the second best ATC unit I've ever had the pleasure of working with".
ATC: "*****, Thanks very much for saying so, congratulations on safely reaching your retirement and good luck. Just out of interest, who was better than us?"
Pilot: "Everybody else... G'day!"
