A Hairy Maclary Day: when things have got a bit on top of you (like meeting Scarface Claw) and you just want to go 'straight back home to bed'
A Lt Worf Day: from the times Worf said 'maybe today is a good day to die' (from a Klingon phrase Heghlu'meH QaQ jajvam). When you know it's all going to be full on, like an invasion or an attack - and you just go into the day full steam ahead and take on whatever comes. They usually end up being pretty good days - often, funnily enough, on a Saturday
A Winnie-the-Pooh Day: when you are a Bear of Very Little Brain
An Eeyore Day: All round gloom... best described in this exchange: 'Good morning, Pooh Bear,' said Eeyore gloomily. 'If it is a good morning, which I doubt', said he. 'Why, what's the matter?' 'Nothing, Pooh Bear, nothing. We can't all, and some of us don't. That's all there is to it.' 'Can't all what?' said Pooh, rubbing his nose. 'Gaiety. Song-and-dance. Here we go round the mulberry bush.'
A Christopher Robin Nothing Day: 'How do you do Nothing?' asked Pooh. 'Well, it's when people call out to you as you're going off to do it "What are you going to do, Christopher Robin?" and you say "Oh, nothing" and then you go and do it. It means just going along, listening to all the things you can't hear, and not bothering.'
A Bisy Backson Day: This is what happens to Christopher Robin when he has to go to school - he is always busy, and will be back soon. This is also what happens some days when there are meetings all over your calendar
