"Passing Through" joke

The German controllers at Frankfurt Airport are infamous for being a short tempered lot. They not only expect you to know your parking location but also how to get there without any assistance from them. So it was with some amusement that we (United 747) listened to the following exchange between Frankfurt ground control and the pilot of a British Airways 747 (callsign Speedbird 206).

Speedbird: "Good morning Frankfurt, Speedbird 206, clear of the active."

Ground: "Guten morgan, taxi to your gate."

The BA 747 pulls onto the main taxiway and stops.

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

Speedbird: "Standby, ground, I'm looking up the gate location now."

Ground (with typical German impatience): "Speedbird 206, have you never been to Frankfurt before?"

Speedbird (coolly): "Yes, several times in 1944, but I didn't stop."
