Wasn't me. Although I am from Holland and was flying back from Duxford yesterday. I do apologise for the behaviour of my fellow countryperson though.
I flew to Duxford Saturday when another classic happened:
London info: OO-XXX, you have a Flight Information Service, squawk 1177, London QHN 1013.
OO-XXX: Squawk, er, 7700, OO-XXX
London: OO-XXX, negative sir, squawk one-one-seven-seven
OO-XXX: Er, 7700, er, OO-XXX
This went on for a while. I hope he did not actually select 7700 during that conversation.
