1. Wes Morgan.
Any Forest fan that doesn't still hold a candle for Wes Morgan is a fool unto themselves. We watched him as a young colt amble confusedly around the pitch. We saw him develop into a solid rock at the heart of the defence (mostly). We loved it when he embarked upon one of his skilful forays down the wing - all bandy legs flailing about like that scary assed spider thing from Toy Story - and lapped up his step-overs.
Look deep into his eyes and you will see that he still loves Forest with all of his mighty heart. In the event of lifting the Premier League trophy, he'll claim that it's his proudest moment in football but we - us Forest fans - know that it will be a lie, a facade, a masquerade: the moment when he smashed in that late equaliser against Notts County from the other side of the Trent is what he really thinks about when his head hits the pillow at night.
Andy King seems like a thoroughly decent chap too. One of those players that never got caught up in the pushing, shoving, backbiting and baiting. He always got on with the job of playing football impressively well against Forest.
It's happened before and it restores the notion that it could happen again. Achieving promotion and then winning the title is a distant dream. In fact, the thought of achieving promotion comes along with the baggage of a sinking feeling that a season in the Premier League would be about as much fun as acupuncture with nine inch nails - accompanied by the music of Nine Inch Nails - yet Leicester's achievements remind us that it needn't be this way. There is more to hope for than three years of narrowly escaping relegation until a rather humdrum mid-table finish and the 5th round of the FA Cup in the fourth season.
It is infuriatingly often overlooked that Forest finished 3rd in 1994-95 straight after promotion from the Championship. The Foxes' season so far opens our eyes to that fact that the Premier League hegemony can be broken - even if it's just for one season.
3. It reminds us of how football used to be.
Football used to be like this once - there wasn't a 'top four' and from one season to the next, a club would veer between a creditable 3rd and then flounce back into mid table obscurity. Moreover, it wasn't always as easy to foresee which club would barnstorm their way to glory and which would fall apart like a cheap Kinder Egg toy.
Anyone who has tried their hand at predicting the results each week during the course of this season knows how maddening it is to do so and at some point has simply resorted to putting very silly score-lines down while shouting out to no one in particular, "what's the point? No team does what they're supposed to do anymore and everything's so confusing and I don't know what's right and what's wrong anymore."
This is what football is supposed to be like - utterly unpredictably bonkers.
4. They deserve it.
Every Leicester fan will have their own very special moment and for most, it will be Jamie Vardy's goal against Liverpool, but there have been so many other moments when the impartial football fan can do nothing but raise a smile and wish their own team did such things.
Just prior to that Vardy goal, Riyad Mahrez killed a ball stone dead as it dropped from somewhere high in the East Midlands sky. He swivelled and pinged the ball right into Vardy's path. He also rather thoughtfully made it sit up just right for him to smash home. We're all football fans here, right? Such moments are what make the game beautiful.
Think about how many times you've watched that 4-0 drubbing of Manchester United from December 1977 - you know the one, the 'lesson in football' performance. Your chest is swelling with pride right now isn't it? Leicester City's demolishing of Manchester City may well be their defining moment.
5. Claudio Ranieiri seems like a nice guy.
They all seem so serious these days. Who can blame them though? The modern Premier League manager seems to spend their whole Sisyphean existence bundled into the corner of a room with microphones jabbed menacingly under their noses while all the time being passive-aggressively asked how disappointed they were with the result which frankly is a polite way of asking whether they think they'll still have a job in the morning, all the while having to fend off hungry rats that want to feed off their Winston Smithesque faces.
Ranieri has no time for this. He has the air of a man who has been criticised more times than he can care to remember and is positively loving life right now. To him, it seems that football is a game to be won or lost and so be it. He's the stand-in English teacher taking the school football team for a season only because he simply bloody loves football and is going to make bloody well sure that all of his players enjoy it because after all, football is there to be enjoyed and played with a smile.
There's no imperative or dictat which requires one to compare the thought of Leicester winning the title (they haven't won it yet) with Forest coming up from the second tier and taking the title - although if you must, this is a very decent place to start, as is this. Each achievement can quite plausibly be enjoyed upon its own merit and when something as unexpected and frankly, as downright bonkers as this happens, it's there to be enjoyed, to be incredulously stared at while tongues loll allover the place in an ungainly fashion.
Besides, one sweet day, a Leicester City fan will be writing such a piece about Nottingham Forest.
