If you're going no further than the sofa, here are some tips on what's worth watching on the box over the weekend.
Pick of the weekend
Live Floyd Mayweather v Conor McGregor, from 12 midnight, Saturday/Sunday, Sky Box Office
After some of the most relentless hype ever witnessed in sport (and that's saying something), the fight of the millennium is finally upon us – and you're welcome to it.
The boxing world is now starting to look as spontaneous as the wrestling one, and don't be at all surprised if there's a re-match between these two already in the hypey pipeline.
Ireland's Conor McGregor, the undisputed king of UFC, takes on the current boxing supremo at the T-Mobile Arena in Las Vegas, where people have paid substantial sums to watch the action live.
For a much lesser cost, you can catch it live on Sky Box Office.
To get you in the mood, here's a documentary called The McGregor Effect. It looks at the nation he inspired, from artists and entrepreneurs to athletes, the documentary aims to get to the heart of the characters and their stories.

Strike – The Cuckoo's Calling, 9.05pm, Sunday, BBC One
The Beeb's drama output has been phenomenally good in recent years, so this should be worth at least a gander, and the cast includes Tara Fitzgerald and Martin Shaw.
Here's the premise: supermodel Lula Landry falls to her death from a Mayfair balcony and the police conclude that she committed suicide.
John Bristow believes that his adopted sister Lula was murdered and the police have overlooked key evidence. He seeks out private investigator Cormoran Strike – a man with a colourful past - who takes up the case.
Diana, 7 Days, 7.30pm, BBC One
The seemingly endless run of documentaries about the late Diana Spencer continues – but chances are this will be the best of the lot.

If that's not enough for you, there's also Diana: Tragedy or Treason? On TLC at 9.00pm.
Ending this weekend
Celebrity Big Brother: Live Final, 9.00pm, 3e
Emma Wills is hosting as the latest CBB event reaches its climax.
This time around there could be a cachet with being the 2017 winner, as this show has been on a ratings downward spiral for years. If it is the last ever run, true fame is there for the winner. Well, you know what I mean.
Afterwards, at 11.05pm, Rylan Clark-Neal does the honours for the last Celebrity Big Brother's Bit on the Side.

The Mist, Netflix
Based on the Stephen King novel of the same name, this spooky tale's about a town in Maine that becomes engulfed in a deadly mist.
Although the scenario remains, the story's characters and sub-plots are brand new, which will probably annoy King's massive fanbase, regardless of whether it works or not.
Included in the changes is what's actually residing within the mist. In the book, the mist contains tentacled monsters that devour the town’s residents. Here, the mist’s terrors are more psychological.
The Ronnie Barker Comedy Lecture with Ben Elton, 10.35pm, Friday, BBC One
Ben Elton, multi-award winning comedian, novelist, playwright, film maker and classic sitcom creator of the likes of The Young Ones, Blackadder and The Thin Blue Line, delivers the inaugural Ronnie Barker Comedy Lecture.
Elton discusses the craft, legacy and importance of the studio sitcom. Sir David Jason introduces the talk with a personal forward about Ronnie Barker and Ben Elton.
The lecture is named in honour of the late, much-loved comedy writer and performer Ronnie Barker, star of The Two Ronnies, Porridge and Open All Hours.

The Help, 10.40pm, Saturday, BBC Two
Based on the novel of the same name, it's about an aspiring white author during the civil rights movement of the 1960s who writes a book about life amongst African American housemaids. Uplifting etc.
Blue Jasmine, 11.40pm, Sunday, RTÉ One
A cracker from late-period Woody Allen, this is about a New York socialite, deeply troubled and in denial, who arrives in San Francisco to impose herself upon her sister. Cate Blanchett is great in the lead, but no one puts a foot wrong here.
Weekend Box Set
The Wire, Sky Box Sets, from Friday August 25
Here's the show that started the concept of word-of-mouth binge-watching, as the vast majority of its fans saw it on box sets rather than weekly on the box. It's also brilliant.
David Simon’s Emmy Award-winning drama stars posh English actor Dominic West (The Affair) as Detective Jimmy McNulty who, along with his fellow investigators, attempts to infiltrate a West Baltimore drug ring headed by the elusive Avon Barksdale (Wood Harris) and his lieutenant, Stringer Bell (Idris Elba).
Later on, Dubliner Aidan Gillan features as political wannabe Tommy Carcetti.
