Isn't that Comic Relief? Mind you, I don't really know the difference (CR only comes round every two years I think?).
Here at work we're in the middle of a sponsored Dress Down Friday. Nothing remarkable about that, we have a Dress Down Friday every Friday so what's the big deal?, but this one is declared to be a 'special' and you're supposed to pay for it! Normally I don't do DDF, I wear the same sort of clothes every day at work, but this time I opted to come in in mufti and drop a couple of one's in the tin. Eases my conscience a bit.
