I'm sure I've heard quite a few of the "unused dialogue" from "Discretion Assured" on my last play-through.
Specifically;
Jimmy - Maybe I should keep one. Just for me.
Kirby - (after the picture is covered) Hey, I was looking at that, you jerk!
Hal - (after the picture is covered) What’d you do that for?!
Mr Martin - (after the picture is covered) Good thing my wife didn’t see me looking at that.
