While Oliver is preparing to eject from his war plane, his radio contact wishes him luck and tells him if he gets captured to ask to be taken to Stalag 13 and 'ask for a chap name Hogan'- a reference to the old 'Hogan's Heroes' TV series (1965-1971).
Lisa reveals that she met Oliver during the war in Hungary, which is where Eva Gabor was actually born and raised.
