MANDELA’S long walk to freedom. The Moon Landings. Live Aid.

As TV moments go, they were all overshadowed on Wednesday night.

Where were you, the grandkids will ask, when Davina McCall made her QVC shopping channel debut flogging her Seven Minute Fitness DVD?

Or, if the title was up to me, Long Lost Flabbily.

A genuinely funny and compelling hour of live telly, with far too many squats and lunges (oh, there were Davina lunges), preceded gloriously by this advert: “There’s now a new and convenient way to return your QVC parcel.”

Not that you’d want to, obviously. Not with the one-time-only special price £17.48, slashed from £21.50.

Plus “£2.95 P&P”, making it £21.43.

A saving of 7p.

One penny for each minute of workout.

For your money, though, you don’t just get a fitness DVD.

No, no, no.

You also get a recipe booklet with all manner of delicious sounding recipes like “tofu meatballs” (grow up), “pumpernickel bread” (seriously, grow up) and egg white and spinach frittata (do you want a slap?).

And to prove the nutritional benefits, she was armed to the teeth with graphs showing gobbledegook like “glycemic index”.

Someone named Max is the brains behind the meals and according to Davina: “He’s all about the basal metabolic rates.”

And an absolute hoot at dinner parties, by the sounds.

I tell you, the things he doesn’t know about basal metabolic rates you could write on the back of a glycemic index pie chart.

Max wasn’t there but her personal trainer was: “Ed has got the science behind it.”

As Davina demonstrated when asked: “Why seven minutes?”

“Well I had previously done 15 minutes and Ed said what about seven minutes.”

Science in action.

Pluck a number from the air and make the rest up as you go.

It convinced starstruck host Debbie Flint who blurted nonsense like: “I love eggs. When we were evolving, people would have eaten eggs. That’s why I love them,” and described Davina as “massively successful in the past”.

She revealed: “I know you’ve been trying for a couple of years to come and make this possible.”

And it would have happened sooner. Had Don King, Frank Warren and Eddie Hearn not got wind and thrown their hats in the ring to promote the event.

Twenty-four months of delicate negotiations and horse-trading later and the deal was struck.

“I love QVC,” Davina announced.

“This is the natural place for me to come.”

We’ve been saying that for years.

She’d do well to learn from Flint’s sales patter which was something to behold.

By the end, the DVD could practically cure depression as well as save marriages.

The punters bought it.

Literally.

Flint gave (highly suspicious) regular updates of how fast they were flying off the shelves (1,000 by 22 minutes, “2,000 left” five minutes later), and from what she said I’d guess 5,000 were sold which, at £21.43 a pop, earned Davina over £100,000.

Not bad for an hour’s squatting, lunging and asking women who’d done her fitness regime: “How much have you lost?”

Roughly?

Sixty minutes of my life, Davina.

Spudulikes…

Corrie’s farewell to Deirdre.

Gold’s fabulous The Interviews following The Two Ronnies with Les Dawson.

Love Island suddenly becoming brilliant with Ben introducing himself: “I suppose you could say I’m a serial dater… not a serial killer.”

Beware of Mr (Ginger) Baker, an incredible portrayal of the irascible old codger that ended with him breaking filmmaker Jay Bulger’s nose with his cane when he realised others would be featured.

Sky Sports F1’s David Croft with a British Grand Prix commentator’s curse: “Fans said they wanted racing. Well, you’ve got it.” Valtteri Bottas’s race engineer on the radio: “Instruction. No racing your teammate.”

And This Morning’s lightning storm advice: “Don’t go out in a boat.” Call me Captain Health and Safety but you probably shouldn’t stand naked atop a skyscraper with electrodes attached to your nether regions singing It’s Raining Men either.

Spuduhates…

BBC’s humiliating Wimbledon 2Day U-turn and belief that One Direction’s Niall Horan’s tweet congratulating Novak Djokovic matters.

ITVBe’s Seven Days With unofficially announcing the end of its celebrity run with Jake Quickenden.

Alesha Dixon giving the British Grand Prix national anthem the Stars and Stripes treatment.

Disappointingly dull C4 experiment Married At First Sight.

Endless shouty arguments, led by gobby horror Harry, rendering Big Brother unwatchable.

Cliche-littered makeover show The Autistic Gardener.

Love Island’s pointless habit of sending in contestants’ exes.

And the revelation that EastEnders’ Big Mo is “on holiday in Faliraki”. Yet not one person asked how she’s affected by Greece’s economic collapse.
