I remember a sheet that went the rounds of the office back in the days before email. Phrases were divided according to the offensive word - all "sh*t" phrases together, etc - and numbered. So instead of saying "Lovely, just f*cking lovely" you could say "eighteen". This occasioned some laughter in meetings where we underlings had "the sheet" and management did not.

My personal favourite was twenty-three - "Go pound sand up your a**".

I like these, too.
