Normally this section of my major final previews is packed full of past meetings but obviously the fact we've got a 16-year-old finalist who hasn't even played on the PDC Tour yet means there's pretty much nothing to see here!
However, the sporting romantic in me wants to include their only known clash in a small Hayling Island competition back in 2019 when Humphries beat a 12-year-old Littler in the quarter-finals.
Littler was asked about this after his stunning victory over Rob Cross on Tuesday night and I found it quite endearing that he focused more on how far Humphries has come since that meeting rather than himself!
Breathtaking isn't it?
If you were shown these match-by-match statistics and were told 'this is what Phil Taylor/Michael van Gerwen/Gary Anderson' managed on his way to the **** final', for example, you believe them and also whimsically remember just how good they were in their pomp.
And here's an interesting fact for you that further underlines how staggering his stats are. Those aforementioned legends above are the only players to have managed four or more 100+ averages en route to a final! Taylor and Anderson have done it in four different tournaments apiece while MVG did it in three. This lad is special.
In Brendan Dolan, he battered a player who made life so difficult for Gerwyn Price and Anderson but the only thing missing from this run - and I expressed this during my preview for the semi-finals in which I foolishly backed Rob Cross - was that he hadn't felt the pressure of playing anyone ranked higher than 20th who could throw a big average in against him.
Well he handled that well, didn't he! Voltage averaged 102 and even won the opening set but Littler bounced back to brush another former world champion aside without hardly breaking sweat.
Littler even said afterwards that nothing has felt difficult. So not only does he make it look easy, he probably actually feels like it is.
The only player who has given him something to think about is Andrew Gilding, who managed to win eight of the 17 legs played despite losing 3-1 in sets.
Humphries stormed into the World Championship as the favourite - and my pre-tournament tip - because there was quite frankly no stopping him. He was winning majors and posting 100+ averages for fun, while he was continually showing the kind of mental strength that was lacking from his game in previous seasons.
Then all of a sudden his momentum ground to a worrying halt when trailing Ricardo Pietreczko in front raucous German support 3-1 in round three and it looked as though nothing could save him. Certainly not his actual darts, which were a brand new set due to a point breaking off one of his usual set.
But after winning the deciding leg of set five, he went on to win six of the next seven legs to pull off an incredible comeback and keep his hopes alive.
Those hopes were hanging by a thread in the very next round when survived two match darts against a heart-broken Joe Cullen before coming through one of most ridiculous endings you'll ever see.
If he does indeed lift this trophy then he'll have no shortage of 'what if' moments to look back on but he left nothing to chance in the last two rounds, averaging 103.5 and 108.74 against Dave Chisnall and Scott Williams respectively, dropping just one set combined.
That's his scary level - especially the 108.74 which is the 10th highest average in World Championship history - and one I really hope he delivers tonight against Littler. Not just because I backed him, but because if Littler can respond with something similar, we could be about to witness one of the most astonishing finals ever.
This is the most eagerly-anticipated World Championship final for generations and all signs point to this living up to the hype in the same way Taylor v Barney did all those years ago.
The fact that it's so hard to call is also remarkable because it's a clash between a pre-tournament favourite and a 16-year-old who nobody thought would be here before a dart was thrown.
But way Littler despatched Rob Cross, who produced big numbers, proved he really can cope with a proper world title contender on the biggest stage of all and really isn't fazed by the pressure whatsoever.
He'll just get up there again and so pretty much the same as if he's been doing it for years.
Humphries' calming and friendly presence obviously won't intimidate him and, if anything, there's been more fear factor built up around Littler's game. He's made grown men buckle up there despite all the experience they had.
Cool Hand, however, is a completely different proposition. One of his strongest assets now is his mental strength and the fact he rarely shows any sign of emotion anymore. He too will stay focused and keep trusting his own process.
Their fast, free-flowing styles will also compliment each other. It will be an absolute darting joy to watch.
This time last year I tipped a nine-dart finish in the final and I'm going to do the same again. I'm even tempted to tip both of them to have one given how spectacular they're playing and the amount of sets we may see but I'll be slightly less bold and stick with any perfect leg at 8/1.
I also love how this bet can never be dead until the winning double is hit.
If Humphries had laboured into this final then I would absolutely be going for Littler but Cool Hand's dominance in the last two games shows he's back to his very best and in no mood to mess around with drama anymore.
The world number one will want to go out and put Littler to the sword - and that's exactly the mentality he'll need to stand a chance.
I'm going to throw in Humphries to fire in the most 180s as well because he was managing 0.43 and 0.56 per leg in the past two matches and if he's in relentless mood tonight, not even Littler's impressive levels will keep up.
Both are landing a prolific number of 100+ checkouts so we can expect a fair few of those as well, especially if we get plenty of sets that we're all expecting.
Finally, sit back and place a fictional £1000 on it being one of the best finals of all time. I'll give you 1/1000!
