Frankfurt air traffic control

exchange between Frankfurt ground control and a British Airways 747, call sign Speedbird 206":

Speedbird 206: "Frankfurt, Speedbird 206 clear of active runway."

Ground: "Speedbird 206. Taxi to gate Alpha One-Seven."

The BA 747 pulled onto the main taxiway and slowed to a stop.

Ground: "Speedbird, do you not know where you are going?"

Speedbird 206: "Stand by, Ground, I'm looking up our gate location now."

Ground (with quite arrogant impatience): "Speedbird 206, have you not been to Frankfurt before?"

Speedbird 206 (coolly): "Yes, twice in 1944 -- but I didn't land."
