As letMfly says, its true- I heard the story from one of the people involved... If memory serves me right, the DAN081 was the last flight of the day, and once landed the Radar Controller could go home (leaving the TWR Controller there until official close time). The Assistant was recording the ATIS and that was when the Controller uttered the words (not thinking that the ATIS was being recorded and might pick them up!).
Thats the gist of it, as remembered through an alcoholic fog
