In the spiritual home of the keirin – where a pizza delivery scooter escorts cyclists around the velodrome – Jason Kenny rode the crust of a wave.
By jumping the field when the derny pulled over, and breaking away to win a record seventh gold medal, Kenny didn't just become Britain's greatest Olympian of all time with the cleanest getaway on a bike since Chris Froome's 50-mile solo ride to glory at the 2018 Giro d'Italia.
Together with wife Laura's bunch of five Olympic titles, they now have enough bullion in the household to make a unique clock face – one medal for each number on the dial.
Not even the most palatial homes in the country, from the House of Windsor to Hampton Court, can rival the Kennys' fantasy timepiece.
Now, they become the first husband and wife to become a knight of the realm and a Dame in the same Honours list.
Quite right, too.
Sir Jason and Dame Laura have been standard-bearers for Brits on the track, and all those who ride under the Union flag, since Team GB dominated the cycling medal table in Beijing 14 years ago.
He is as down-to-earth as an Apollo spacecraft splashdown, and she is a giggling Home Counties girl-next-door, but don't be fooled by his wholesome Bolton virtues or her dainty plaits.
Sir Jason and Dame Laura won't expect us to bow and curtsey when they enter the room, but beneath the illustrious couple's charm lies a pair of ferocious competitors with a golden touch.
Before Jason Francis Kenny unfurled his JFK moment in the Izu velodrome at the deferred Tokyo 2020 Games, Sir Chris Hoy – the cycling royalty with whom he was level on six gold medals – sent him a good-luck text after a disappointing week in the sprint competitions.
The cheeky beggar returned serve with a two-word response: “Thanks, Dad.”
He also enjoyed going past Hoy, godfather of Team GB's blazing saddles, at No.1 in the pantheon “because I know it will annoy him!”
To be trackside when Kenny caught Australia's Matthew Glaetzer asleep at the handlebars, and made his break for glory, was not only a privilege which made you believe a man can make a bike fly.
For this scribbler of notes, it was the highlight of Tokyo. One of the greatest things I've seen in 40 years on the sporting beat.
It was a measure of the respect in which Kenny is held when flying Dutchman Harrie Lavreysen and Malaysia's Mohd Azizulhasni Awang, who took distant silver and bronze, lifted the double keirin champion on their shoulders at the medal ceremony.
Sir Jason's stash of bullion is the best magnificent seven since Yul Brynner, Charles Bronson, Robert Vaughn, Steve McQueen, Eli Wallach, James Coburn and the German one rode into town.
Not to be outdone, Dame Laura's procession to Olympic gold with Katie Archibald in the inaugural women's Madison was also in a class of its own.
She travelled to Japan as a working mum who left the couple's three-year-old son Albie on a grandparents' care roster – and came home with her fifth title, plus a silver in the women's pursuit.
Although she matched Charlotte Dujardin's total of six Olympic medals, 29-year-old Dame Laura has two more golds than the equestrian queen and she joked: "I feel like we're just making up these records as we go along!"
By the time she is done, and with Paris 2024 in her sights, Sir Jason may discover he's not just been overtaken as Team GB's most successful Olympian... he may not even be the most decorated cyclist in his household.
