Funny story...
I used to work at an airport many moons ago, and I heard this story (no idea how true it is, but it was one of many).
A Lufthansa flight was repeatedly asking for taxiing directions. Ground were getting a bit fed up. The Lufthansa pilot came over the radio and said "Sorry, but I have never been here before".
Someone piped up: "Zat iss not true! He vas last here in 1942!".
