Nelson Mandela is probably the closest thing to a living saint we've got – he's so kindly and warm, like Santa Claus, the Werther's Original grandpa and Ronald McDonald all rolled into one.

Nelson Mandela has got nothing but pure undiluted joy for every single person in the whole wide world – or at least he would have, if Naomi Campbell wasn't such a massive angry bitch all the time.

There's a big concert being held in Hyde Park for Nelson Mandela's 90th birthday tomorrow, and Naomi Campbell was on call to introduce some of the acts. However, since her recent air rage conviction it's been reported that Nelson Mandela himself has personally intervened to remove Naomi Campbell from proceedings. Hopefully there's still time to replace Naomi with a friendlier celebrity – perhaps Amy Winehouse's husband or the ghost of Saparmurat Niyazov or something.

Hey, ever wondered what it'd take to turn Nelson Mandela into a dick? So have we – the man seems so benevolent and wise and compassionate that he's even managed to spend considerable lengths of time with Geri Halliwell without trying to smack her head off with the back of a shovel just to shut her up. He's an unflappable superman.

But what presses Nelson Mandela's buttons? Would he lose his shit if you kept poking him in the eye with a detached animal penis? Probably not. If you kept filling his shoes with gravel every time he turned his back? Again, probably not. If you sat three feet away from him playing the accordion as loudly as possible when he was trying to discuss ways to counter the spread of AIDS in Africa? No chance.

If you were arrested for furiously spitting at policemen on an aeroplane just because a bag with some of your stuff in it has gone missing? That's more like it. Nelson Mandela hates it when people do that. He hates it enough to personally intervene and publicly humiliate anyone who does it by uninviting them to his birthday party. 

And since Naomi Campbell is the only person on Earth who's done that lately, she's copped the full brunt of Mandela's grumpiness. Apparently Naomi Campbell was going to be used to introduce acts at Nelson Mandela's big birthday concert in Hyde Park tomorrow, but since she made such an arse of herself on the plane – and subsequently when she claimed she was just reacting to racism – she's apparently been told that her services are no longer required. The Press Association reports:

A source close to the concert said: "People were disappointed by what happened – in the past she had spoken to Mandela about her anger. It's not the behaviour of a charity ambassador. Mandela would have had a say. It's fair to say he was behind the decision. There's an aspect of him being upset by the whole situation."

What's probably most hurtful to Nelson Mandela is the fact that when Naomi Campbell was lashing out like a berserko fruitcake on the plane, she was wearing a baseball cap promoting Mandela's charity 46664. Attacking the police in a charity baseball cap never goes down particularly well, but we assumed that Naomi Campbell would have got away with it – surely most people assumed that 46664 was just a running total of servants who Naomi Campbell had punched in the face so far that week.

Anyway, full credit to Nelson Mandela for standing up to Naomi Campbell so bravely. His courage knows no bounds – because, honestly, 18 years in prison on an island is going to seem like nothing once Naomi Campbell hears about this snub and dedicates the rest of her life to trying to push a smartphone through one of his eye sockets.
