Paper Work
I once listed the recipients of a report at work on the front page so that the first initials of the first names spelled out "BASTARDS ALL" vertically (including the space). It included three directors and two VPs. Not a one noticed, of course, but it was posted in the lab for about a year as the "Standard" distribution list, used by all for future report distribution.
Bless their pointy 'lil heads.
