No wear, no tear.
Unlike the toy cars mum and dad got us kids for birthdays and Christmases.
Built of sturdy metal and with firm plastic tyres they were a treat, for a couple of years until our exploits in the shingle yard with them wore them down.
But Lego?
You could leave a little model car made of them outside for as many years as you like and I doubt they would corrode or dissolve.
Oddly enough I can't recall coming across Lego until I was in my teens, at a time when they had been selling across the world for a couple of decades.
When we were kids we had Meccano.
Strips and slices of hole-punched metal pieces and hundreds of little nuts and bolts of which many ended up seeing the interior of the vacuum cleaner.
But, like Lego, it encouraged the use of the imagination and the hands to piece together whatever it was you wanted to build.
And we built everything imaginable.
Then dismantled our hours of toil and then built something else.
They were standard kits of green and red coated parts, whereas Lego comes in a huge range of colours and now shapes.
Not just cubes and blocks any more.
Ole Kirk Christiansen would be very proud ... not to mention enormously wealthy if he were still with us.
This inspired Danish chap came up with the idea of creating building blocks for kids.
Blocks which would attach themselves to other blocks so that there was no limit to what could be created.
He founded Lego in the town of Billund in Denmark in 1932, and by 1949, after initial modest production and trading, it became the world's leading brand of toy construction kits.
The headquarters of what is now a major industrial light on the world landscape is still in Billund.
They keep making the kits and we keep keeping them, which is remarkable.
I daresay that in terms of how many individual pieces have been stamped out since 1939 you'd probably have to talk in quadrillions ... which is a number with 15 noughts behind it.
And the kits they come out with today are remarkable and naturally cash in on the film and book-driven fads of the eras.
I spotted a Star Wars Lego kit which appeared to be Darth Vadar's great ship and the price tag was $1499.
You could probably buy a cheap runabout car for that.
Or you could scale it back a little and settle for a Lego kit of the Hogwarts College from Harry Potter for only around $700.
While we may gasp at such price tags, the fact is they sell, for Lego is ageless and timeless and can hook the generations of 2019 as effectively as it hooked the generations of 1939 eight decades ago.
Today there are global clubs and organisations sparked by Lego.
There are even professional Lego model builders who stage exhibitions, and there is no limit to what can be built.
Someone in the States has built a model of the Washington National Cathedral and they used 500,000 pieces.
That's half a million.
That's a lot.
Wonder how many physiotherapy sessions they needed for the old fingers after that effort.
I have seen a couple of Lego exhibitions and have been amazed at the skills and imagination the creators of the artworks possess.
And such events draw great crowds.
So no real surprise then that television has constructed a Lego kit of its very own. An Aussie made Lego kit rather than something stamped out in Denmark.
Here we have the latest addition to the "reality" family of shows (a great many of which drift over from across the Tasman) and it all hinges on who can make the best of a box of Lego.
Teams of Lego aficionados, many of them clearly almost possessed by the plastic joints placed before them, go into battle to build what the judges determine to be the finest creation on the night.
The title determines that they are "masters" of Lego construction so expect some rather imaginative offerings.
Be cautious letting the kids watch it though.
Their inevitable pleas for more blocks to allow them to make a replica of a North Korean nuclear missile will cost an arm and a leg.
Lego Masters Australia, TV3 at 7.30pm Wednesday: The Aussie Lego legends go into battle with the world's most enduring construction kits.
Were there to be a Lego Masters US version whoever built the best wall would likely take home the rewards.
ON THE BOX
Dancing With The Stars, TV3 at 7.30 tonight: It has come down to the final stages ... apparently.
I have to be honest here and admit I have not caught more than about three minutes of dance floor action, for the simple reason I am not all that inclined toward theatrical dance floor action.
But this series, like the previous issues, draws a good audience and I guess that's down to the familiar faces taking part in what is for them an unfamiliar pursuit, and the fact it is a knock-out event.
The field of dancing duos gets culled by the week.
Gordon, Gino and Fred's Road Trip, TV1 at 8.30pm Thursday: Given the individual and diverse backgrounds of these three chaps it's a wonder any of them managed to get a word in.
Gordon Ramsey and Gino D'Acampo are celebrity chefs who live in the media spotlight, and Fred Siriex is a celebrity front-of-house maitre 'd lad.
All have done time (lots of it) on television so getting them together for an often unpredictable and noisy road trip was always on the cards.
They tour each other's patches — Scotland, Italy and France.
And oh yes, there are some "interesting" verbal engagements.
